9. HP Prime Graphing Calculator Review – Another Best Graphing Calculator for SAT
HP has released some excellent calculator references. We love his “Prime” model for many reasons: it runs extremely fast, its acquisition cost is relatively low, the battery life is phenomenal, and the finish is of high quality. Unfortunately, there are disadvantages with the HP Prime: the screen is reflective, it restarts randomly, which can be very annoying when you’re in the middle of an equation, and even if it offers a touchscreen, we found the keyboard interface more efficient for working. High school and college students will appreciate this type of screen, but we do not recommend engineers who use their calculation tool very regularly.
From the beginning of this ranking, and in some of the reviews you will read while browsing my site, I am talking about Fashion Review. I have prepared a little paragraph to enlighten you on this subject still unknown to some, but that is important.
The Exam Mode is an option present on some calculators of the market, whether scientific or graphics and which will be soon obligatory during the examinations and the official national contests. The Ministry of National Education has issued a statement quite recently, which states that as of 2018, the types of calculators that would be allowed during national exams and exams would be:
 Calculators not programmable and without alphanumeric memory (it is the most basic calculators that it is)
 Scientific calculators and programmable graphics, provided they are equipped with the famous Exam Mode that we are talking about.
From a technical point of view, this is what the review mode offers:
 It allows blocking momentarily or permanently the access to the memory of the machine
 It makes it impossible to exchange data between the calculator and other devices via WIFI, Bluetooth technology, or any other remote communication technique.
 Scientific calculators that feature this mode also feature a light diode often placed on the upper body of the machine to be as visible as possible, which starts to flash when the review mode is engaged.
 To unplug it, it is necessary to connect the tool to a computer or other calculator via a cable, often USB or micro USB, which is obviously prohibited during exams.
As you can see, the exam mode is there to minimize attempts to cheat and cheat using calculators during exams. The Ministry of National Education has taken these steps after noticing a resurgence of this type of cheating in recent years. This measure is, therefore, more preventive, unlike the punitive measures that are already applied. The latter is, however, very strict, and one might think that they are enough to dissuade the smart guys, but this is not what the most recent studies show.
You now understand why the presence or absence of this Exam Mode on a calculator is a crucial point in your purchase decision. More and more manufacturers are equipping their newest products with this mode, but be careful, a lot of machines on the market currently do not offer it. In the long run, they should almost all offer it, but this is not yet the case.
So, if the user of the calculator you are going to buy will be required to take exams in 2018 or later, keep in mind that only those with exam mode will be accepted in the room. On the other hand, if it is for a personal or professional use, or that there are no exams to the horizons, this option is surely useless!

A scientific calculator helps with many problems of algebra, a pocket calculator that can do a lot more,
So that your decision is not based solely on the consideration of Texas Instruments calculator or Sharp calculator, you should take a closer look at our purchase advice before buying. Because we not only present you the best models in our Graphical Calculator Comparison 2017 but also provide you with a lot of additional information.
1. What is a graphical calculator?
Story
The first graphic calculator went into production in 1985. The manufacturer was the company Casio. His name: Casio fx7000G.
A Graphical Calculator, like the models in our Graphical Calculator Comparison, unlike other calculators, is capable of displaying not only complex numbers but also graphs and charts. With it, tasks of the socalled analysis, which otherwise require the use of a ruler, a compass or another drawing tool, can be solved. With him can further
 Problems of mathematics are made clear
 to experiment on graphs,
 Laws of mathematics are worked out and
 Guessing results can be quickly and easily verified.
The calculators have an extra highresolution display for the complex presentation. Unlike other computers, which have only one input line, there is the possibility to use several lines for the input of the invoice, and also the results are output over several lines. Many models also have a color display with a backlight. As with other scientific calculators, they can program certain content on the calculator.
2. Which computer types are there?
A test of graphing calculators, of course, mainly deals with the properties of graphing calculators. However, it makes sense to know other types of computers before deciding to buy a graphing calculator.
Category, Features, and suitability basis  

calculator  A suitability basis computer or desktop computer has the usual basic operations. Also, percentage calculation is possible with him. Larger and complex bills cannot be solved with this calculator, but the memory of the products is too small.  
Scientific calculator  A scientific calculator, like the desktop calculator, has the usual basic arithmetic, but can also solve scientific functions and equations with complex numbers. The computers have a large memory and are used both in school and study as well as in the profession (engineering professions).  
graphicscapable calculator  A graphing calculator can represent function graphs and diagrams. A graphing calculator has a very highresolution LCD screen. Many models can also be programmed. The following types are distinguished:1st numerical calculatorNumeric calculators can solve equations. Derivatives can also be specified as nutritional values. 2. symbolic calculatorA symbolic calculator allows the user to calculate with letters. So it’s about solving algebraic equations. 3. CAS calculatorA calculator that calculates based on the computer algebra system is referred to as a CAS graphing calculator or graphing calculator with CAS. It solves problems of dynamic geometry, as often seen in architectural drawings. Such a graphing calculator can represent movements and deformations of figures. The acquisition of measured values, as they are often required in technical professions, is possible.  
Due to the lack of functions, a simple desktop computer does not require a lot of user familiarization. To understand a scientific calculator or a GTR calculator, the complex operations require a longer settling time.For that, you should bring a, little more patience. 
3. Types of graphing calculators
By having the ideal calculator, you can solve complex mathematical or scientific equations quickly, use them in the classroom or at work and is a necessary tool for both students and teachers.
The types are divided according to their abilities or form to find the desired answer, some scientific calculators are basic, with a small screen that only expresses numbers, symbols or units, some more advanced can graph, make scientific notations, trigonometric functions, logarithmic or exponential thanks to its large screen, which improves the experience when manipulating it.
On the other hand, there are also those that have buttons or quick accesses that facilitate data entry, as well as those that have information storage capacity, drawing diagrams, statistical calculations, analytical tables and more.
3.1 CAS (Algebra Computer Systems) vs. No CAS
Both incorporate advanced features that allow to work with variables or solve equations. However, the No CAS answers only the minor problems, but they are useful to become familiar with the manipulation of scientific calculators, and in most of the occasions, it is advisable to start with models No CAS.
The calculators are also differentiated by the expression of the formulas, the number of variables capable of processing or display format. In the most recent models, mathematical expressions similar to how they are in the books are thrown, so that it becomes digestible for the students and easy to explain for teachers.
CAS calculators process expressions with symbols, a useful feature for professionals and researchers, which is why they are more expensive. NonCAS calculators, for their part, produce expressions in syntax, simple for apprentices and are much cheaper.
3.2 RPN (Reverse Polish Notation) vs. Algebraic Modes
Scientific calculators cover a large number of areas, and your need is probably to make calculations in the environment of electrical engineering, chemistry, astronomy or physics; to meet this requirement, there are RPN or Algebraic.
The best known are algebraic, which assimilates the data in the order commonly known by most teachers and students. Some calculators are convertible, and you can enable it in RPN mode. Also operations would be done in understandable order saving time, processing and storage space.
3.3 Recommendations for students
As we had mentioned before, the application of scientific calculators depends on the level of education you are in, whether secondary or university. Some are used for algebra, mathematics, trigonometry and even business and finance, others for their abilities respond to requirements geometric calculations, areas of a triangle or other formulas.
The calculators for high school courses, however basic they may be, apply to mathematics, statistics, probabilistic and offer functions of dispersion graphs, basic graphs, absolute values, scientific functions, determine maximum or minimum values or exponential dispersion.
Several models of them are applicable for university classes, but you must be attentive to the specifications of them and analyze if they work for you. On the other hand, it is also recommended to consult your school or teacher, as some do not even accept instruments with such advanced functions.
3.4 Recommendations for teachers
Every teacher must understand how the calculator works, that is why several brands offer training courses to teachers so that they know all the functions of the device, they can get the most out of it and eventually transfer the knowledge to the students.
The Texas Instruments offers a device called ViewScreen, which works as an overhead projector to enlarge the calculator screen, useful for demonstrations of use, formula entry or to facilitate the method of teaching the subject or instrument as such.
Similarly, other brands offer free trials for a limited time that allow experimenting with the calculator, before buying to ensure that it meets expectations.
4. Function of a graphing calculator
The graphing calculator like any calculator, it serves to determine results in mathematical tasks electronically. However, graphing computers are a contemporary and modern support that comes with a touch display and graphical representation. The experimental approach to computational tasks is supported and can be individually adapted to the knowledge and understanding of the individual student. While a classic calculator only shows the result and “conceals” the calculation method, students with a graphing calculator can follow all the steps and decide on their calculation method. Anyone who is at loggerheads with mathematics and faces an unsolvable task with the required explanation for the solution, can build this understanding with a graphing calculator and renounce from then on explanation. However, one should not forget that a graphing calculator only displays the correct result if the task is entered correctly and thus calculated precisely. The large high – contrast display can be operated by touch on some models, while in other models it is only used for graphic representation and operation is continued via the keyboard must be done. Graphing calculators are an innovation in modern schools and are intended to bring modern technology into classrooms for mathematics lessons.
5. Applications of graphing calculators
 Modern calculators, by elementary that have utilities that facilitate learning, teaching, practice and general use of it.
 Some models have the NoteFolio a letter keyboard designed to take notes during class to take them to a Word document and then share them.
 On the other hand, there is also the StudyCards, designed to make virtual memory cards to store information that is not even related to calculations.
 The LearningCheck is similar to taking notes, but this time has generated a list of questions, comments or reviews during learning.
 For its part, activity helps teachers to create exercises based on the students’ approaches and in turn share them with the rest of the class.
 There are also models that incorporate spreadsheets for statistical analysis, and the best thing is that most are compatible with other additional applications to increase their versatility.
6. Advantages and disadvantages of graphics calculators
The fact is: our offspring is growing up with innovations and modern technologies. It is precisely this aspect that is exploited by the manufacturers of graphics computers and has brought to the market a computational aid that, due to its operation and functionality, is recognized by all students. The color display in enormous size makes it easy to present both computational results and graphical representations and to recognize them without further ado. By taking advantage of ease of use and transforming pure computational steps into graphs, students understand the math much more easily and identify with the solutions. The unconventional approach to arithmetic tasks is the focus of graphical calculators and makes the lessons varied and modern. However, there is a large selection of graphing machines whose operation differs and whose features come up with some differences. Anyone who has become accustomed to a brand and has learned to use the graphics calculator, should not retool and rely on a model from another manufacturer. This could be the only disadvantage that can arise when using graphing machines.
7. Purchase criteria for graphing calculators: You must pay attention to this
To get this kind of calculator for free or to buy a cheap graphing calculator is, unlike the base or desktop computers, relatively difficult. Most of the prices of these models are quite high. It is therefore important to plan the purchase, so you will not later find that the computer does not fit you and your needs.
7.1. Operating mode
Many users prefer solar cells with an algebra calculator. In this case, no batteries have to be bought. This is very environmentally friendly. Whether scientific calculator or desk calculator, most models are designed so that they also get along with the low light. However, with a GTR calculator (another name for the graphical calculator) battery operation is standard. Either the calculator is equipped with normal AAA batteries, or it is kept running a lithiumion battery. A best graphing calculator should, if possible, have batteries, as they can be recharged without problems over and over again. But of course, in case of doubt, do not choose your model according to its operating mode.
7.2. display
If you do not use a calculator online, then a Texas Instruments or a Casio calculator has a four to 16line display. Here, the more, the better. So you, have a better overview of the bills. It is also nice if the bill on the pocket calculator display is displayed naturally. So the calculations look similar to those in a math book. Especially with fractions, one profits from a natural representation. Whether it’s a Texas Instruments calculator or a thirdparty product, most GTR calculators typically have a natural appearance. Of course, a scientific color calculator is always a bit more expensive, but better suited for the types of calculations that are tracked with a graphical calculator.
7.3. programming function
A programmable calculator has an internal memory especially for storing programs. There is also an extra mode for program input and a text editor. If you choose a programmable calculator, you can load various math programs or geometry programs to help solve specific tasks. You can also play games via your calculator.
Tip: Pupils and students should not just buy any model. Very often schools and universities demand a special model. If all computers have the same functions, each participant has the same prerequisites for exams. In addition, teaching in the group is easier if the same operation of the device can be referred to.
7.4. CAS Software
The calculators mostly include a Computer Algebra System (CAS) program with the purpose of being able to offer mathematical results with a speed higher than expected and thus be able to obtain the answers in an efficient way, thus fulfilling the purpose of the purchase made and gave us the complete assurance that a profitable investment was made.
We consider that if a graphing calculator has useful advantages like the mentioned software as well as the tactile option we think that its price is high. In our search to locate a good and economic graphical calculator, we are mortified to know how much it costs if we think that these qualities have the most expensive artifacts, but it is necessary to think that the technology advances and the devices every time obtain characteristics of the modern articles that We use them nowadays and most of the products are that good and better yet cheap.
7.5. Memory
The graphing calculators have a RAM and ROM memory that vary according to the amount they have to perform mathematical operations. This will give you greater speed at the time of using them and will allow you to produce immediate results proportionally to the haste with which we need them when you turn it on and access the desired procedure.
They also have storage parallel to the internal since they have the option of inserting a mini SD card through a slot. To save the complex mathematical or algebraic procedures that we need, this space is presented as a useful alternative and archive the graphing and numerical operations that are relevant. Later they can be downloaded using a USB cable; a graphing calculator becomes an ally of our children as well as our work if in the work environment we rigorously use the numbers.
7.6. Accessibility
Adhering to the technological avantgarde, today’s calculators are no longer the same as before, where you can only access their functions through their buttons. Nowadays, a more modern navigation facility has been coupled, since some have a tactile option, very appropriate for the use of those who already adapt to use our smartphones in a fingerprint way.
With the option to have two options open to copy and paste, we can store the information and save it effectively and without concern. Not only through the fingers, we can use a graphing calculator, but through digital pencils, the use of an apparatus of this branch will join our demands.
7.7. Battery and power
It should be noted that all devices work with a battery, so the user will not be interrupted by the change of batteries or because it was worn to half a class. The best is that the power source is rechargeable, some are charged via USB, but others are made by wall connections.
7.8. Easy to use
It is key for beginners to look for features that facilitate their use. Certain calculators have touch screens, buttons that allow you to scroll through functions, shortcuts and even split screens that will apply the vision between graphics or equations simultaneously.
There is equipment with preloaded formulas, where you will only have to enter values to know the answer easily, as well as teams that link with paper impressions to superimpose expressions or graphs with which you are working.
7.9. Other useful features
The 3D graphing calculators make you understand the effect of some functions better since the inclination or height is appreciated.
When a computer includes connectivity via USB, it will be easy to manage the files or share information. Those that have this modality are linked with word processors or spreadsheets.
Also, your calculator will be updated and ready to install new applications, even when the device is for school use, which will not detract from its usefulness in higher learning levels.
7.10. Price
In the market there is everything, and you can find it from $50 to $150, and the price depends on the capacity of it. If you want a model that is affordable, but of good quality, it is better to invest in the No CAS models, these work well for students or certain types of professional calculations.
Consider also that if you buy a basic model, and you intend to install additional applications, the price could be higher in the long run.
If you are looking for a specific instrument for certain subjects, you may want to acquire a used calculator whose price would be low, and similarly, at the end of the course, you could resell it to buy a more durable utility.
Among the most popular, Texas Instruments are the most expensive, since by tradition they are versatile and applied to students and teachers. On the other hand, the Casio is cheaper and even more straightforward to use. Both are good options and choosing between one, or the other will depend on your need.
7.11. Warranty
Considering that investment is important and that it is also an instrument of study or investigation, the least you should expect from it is that it has outstanding quality. The guarantee is a good backup, most come with a one year warranty against factory defects, but others include damage due to use or even nonconformity with the device.
Good calculators are manufactured with the robustness that is needed to withstand a blow by involuntary fall. However, we recommend ensuring that the warranty responds to a malfunction of the same.
7.12. Colors
The graphing calculators show quality in colors and resolution in their LCD screen that gives much more dynamism when using it. This advance is opportune for the usability that will be given by the students that need to use it. Adapted to the avantgarde of colors and dynamic backgrounds that give freshness to the complexity of scientific processes that are carried out in it.
As for students, for professionals in engineering, chemistry or physics where they must perform mathematical operations, some graphing calculators break with the paradigms of gray. Bringing color and some visual freshness to those who use it, these devices allow to stick to the demands of the modern.
8. Care and cleaning tips
Your Graphical Calculator Comparison Winner does not require any special cleaning or care. If you have a model with lithiumion batteries, you should occasionally pay attention to the care of the batteries. With regular maintenance, you can extend their service life so that they can exceed the three years specified by the manufacturers. As the maintenance looks exactly, we explain in the following:
 Always protect the battery from excessive heat and moisture. The most optimal for the battery is a dry and cool room climate between 0 and 25 ° C.
 Charge the battery regularly. Also, make sure that it rarely discharges completely.
 Use the graphical calculator Download to update the operating system of the computer at regular intervals. The graphical calculator software contains programs that can optimize the battery life.
9. How to use a graphing calculator?
Nowadays, graphing calculators have become particularly powerful. The use of this device is essential for students in the scientific field. Faced with this potential, many people find it difficult to use these machines properly. That’s why we offer some guidelines to help you get started with this material.
9.1. Detect essential functions
For important features you need, refer to the case to detect the main functions of the device. Indeed, the inscriptions are not the same, from one model to another. On some machines, you have to press “Shift” or “Fn” continuously to have certain functions.
9.2. Determine the order of the keys
If this is the first time you use this kind of machine, you will certainly have trouble figuring out how to enter numbers as well as random signs. Depending on the model you have chosen, first, enter the numerical value before pressing the sign or the opposite.
9.3. Learn how to calculate the power
To make sure you know how to calculate the power of a number, refer to the corresponding function to make sure you have understood how to enter the random sign and the numbers. To do this, start by performing a simple test and if the result displayed is correct then you have followed the correct order. Otherwise, repeat the operation by doing the opposite of what you did before.
9.4. Train with trigonometric functions
To master the sine, cosine and tangent functions, train yourself to the striking order as well as to the angle unit. To do this, perform a sinus test using a simple angle. Take the example of the 30 ° sine which is normally 0.5.
On the calculator, check whether to enter the number 30 first or press the “sin” button. If the answer is correct, it means that the device requires an angle in degrees. On the other hand, if the result is 0.988, this indicates that the machine needs an angle in radians. Use the “mode” key if you want to go from one unit to another.
9.5. Watch out for long calculations
To succeed in making long calculations with your machine, be very rigorous. Use parentheses for priority calculations. Use the “()” keys and remember that you must always close the parentheses that you have opened for correct results.
Also, check that parentheses are in place to avoid the risk of error in your evaluations.
9.6. Determine how to store and recall results
Try to master the memory functions of the machine when doing evaluations with intermediate results. This can be done in different ways depending on the model you purchased. Use the “MR” key to remember the last answer.
Press “M +” or “STO” if you want to add the result to the memory. Otherwise, select the “MR” or “RCL” buttons to enter the value in the calculation.
10. Manufacturers and brands
Unlike other products, with a GTR calculator, the selection of manufacturers and brands is not that big. The most common ones we present to you here, which always show up against a graphical calculator test.

12. Various tips
To finish our world tour of the graphical calculators, let me give you some simple advice, that you will follow or not of course!
13. Ask yourself the right questions
Before you throw yourself on your credit card or checkout, ask yourself the right questions. This is what I call the needs determination phase, and in my opinion, it’s a phase that should be present in absolutely every decision process in your life! Too often we make hasty decisions, which we then regret. The only way to avoid this is to ask yourself questions! Each decision will have its own set of specific questions, but basically, you need to be able to identify what you expect from the decision you are going to make. It’s more telling with examples, so let’s go with some simple questions obviously related to buying your next graphing calculator:
13.1. Who will use it?
As you have probably noticed if you have already been a little on my site, when talking about a graphing calculator, it is indicated in the vast majority of the time for what type of person it is designed, and for what specific use it is effective. Based on this, you will be able to make your decision in a thoughtful way, taking care to be careful to acquire a good that is suitable for the use you will have. for example, if a machine is recommended for high school students, it is better not to buy it for a high school student who may be lost or in trouble. This does not mean that the graphing calculator in question cannot fulfill the tasks that are requested at the college, but that may mean that the interface is more complex than what is usually proposed to college students. The reasons may vary, but I advise you to follow the advice of users to avoid the risk of misunderstanding and other errors.
13.2. How much do I want to spend?
Obviously, the money will have to be mentioned at one time or another! Once again if you have already been a little on my site, you have realized that there are graphing calculators for all budgets! Ask yourself the question of the budget you want to allocate to this purchase as soon as possible this will allow you to save a lot of time in your research. You can focus on the machines that follow your budget, and thus avoid wasting time with the hundreds of models too expensive or too cheap for you.
As I said, these two questions are examples. These are, in my opinion, questions that are important to ask you before buying your graphing calculator, but there are obviously plenty of others. Everyone will have their own questions to ask in order to direct their research to the tool that best suits them.
13.3. Anticipate the worst
Anticipation is something very important in life! This is also the case in mathematics, and with the material you use. I’ll explain quickly: If you’re using a batterypowered calculator, think about putting a game in your bag. it may seem more logical for some of you, but I prefer to remember! Similarly, if you are using a machine that works with a rechargeable lithiumion battery, maybe you could invest in a small external battery that will allow you to cope with the hard knocks. In addition, this battery will serve you most of the time to charge your phone, belief in my experience. But you’ll be glad to find it the day of an exam when you see your calculator go out slowly! And yes you have to think of everything! It’s nice to have hightech products high performance, but if they have more batteries or more batteries, they are useless! So, as the famous saying goes: Better to prevent than cure. So anticipate.
Here I think we made a serious turn of the matter. If you have taken the time to read my entire site, you must now be part of the graphical calculator! I sincerely hope this site has at least a little help in making your choice or understanding some aspects of the graphing calculator that was still unclear to you. As I told you in my article about me, do not hesitate to contact me to give me advice, advice, ask me questions, or just to say hello! It’s always nice to have feedback from readers!
Now is the time to go through the mysteries of mathematics, armed with your new graphing calculator! Have you not yet? What are you waiting for? I will not deliver it to you anyway!?
14. Acceptable Calculators For the SAT
The SAT College Board prevented all calculators that have the latter features:
 A “QWERTY” keyboard which is like a computer
 A stylus or pen.
 The ability to communicate wirelessly or via the infrared port.
 Makes sounds or has a tape printout.
 Applies an electrical socket for power supply.
This gives almost all calculators as fair game. The SAT is more tolerant than any other official testing organization.

15. Online options
Online calculators represent an economic alternative compared to physical calculators, they are also recommended if the use is temporary, however, you need a computer to link you to it.
There are applications for calculators free of subscription payments; however, the use could be limited, forcing you to acquire additional functions that you might need.
One of the best rated online options is the Desmos graphing calculator, it works at an academic and professional level and is available for PCs, Macs or Android or Apple phones or tables, although there is also the Geogebra with practically the same specifications and apart from developed by prestigious universities worldwide.
Online applications allow you to make tables, solve quick equations or generate graphs and you can also create a profile where you will remember the recently used equations.
The disadvantage of being dependent on an online calculator is that you need a computer or other equipment that could run out of battery at any time, and that apart has other functions that could interrupt the use of the same, in addition to the connection to the internet It is essential that you escape from your hands guarantee when you want to use it.
 A graphing calculator can display function graphs and diagrams on its display. He is used in many schools from the upper grades in mathematics education and in the study he is a frequent companion. But not only within the school or student training, but he also finds use, even in technical professions, eg. In engineering, it is used.
 Graphing computers are available in different variants. A numerical calculator can solve equations and derivatives, with a symbolic calculator algebraic calculations (with letters) can be performed. A CAS calculator solves problems of dynamic geometry and represents movements and deformations on figures in a graph.
 A programming function in the math calculator allows you to play additional math or geometry programs on the calculator. So you can also solve more specific tasks.
Too often, you have to break your head in everyday life today. It’s about making decisions about a variety of small and large problems. Nice if the head gets relief in other areas. Especially when it comes to solving complex mathematical problems in school, study or work. Here, the head often smokes also. A remedy is provided by various calculators, which take over the work and protect the head from overheating. Whether you use a calculator online from the Internet or a portable Casio calculator model is up to you. It is important to clarify in advance which computer you need at all.
