This Buyer’s Guide provides information on technical specifications, capabilities, and potential pitfalls of the best graphing calculators. Once you know a calculator’s capabilities, you will determine if it will perform the essential functions you need.
Whether you have a child required to use a graphing calculator for a class or a professional and need one for your job, finding the right graphing calculator can be challenging, especially if you are unsure what they actually do. It’s important to understand the particular calculations needed for a class or a particular profession to choose a graphing calculator with the specialized knowledge centers you will need.
Buyer’s Guide
Determining the required level of capabilities is the first step in picking the best graphing calculator. Graphing calculators have a wide range of specifications that are also important to take into consideration.
Capabilities and Specifications
The best graphing calculator for you will perform the functions you need it to. If you need a calculator for complex electrical engineering, we would recommend a more advanced model. Electrical engineering includes specific variables and equations that are essential for performing data analytics. To ensure you buy what you need, consider looking at the calculator’s manual. In the manual, you’ll be able to find every capability for that product. Search for the capabilities that you need to match your desired task. Performing statistical analysis may require capabilities that include logical operations. By searching in the manual for these capabilities, you will determine if and how your calculator can carry out these functions.
Graphing Calculator vs. Scientific Calculator
Scientific and graphing calculators are the two most popular types of calculators. Each can do typical operations, but the biggest difference between the two is their functions.
With a scientific calculator, you can perform a range of complex calculations, including Trigonometry, functions like Cosine, Sine, Tangent, and their inverse functions. Plus, it can also handle exponentiation and logarithm calculations used by students taking math and science classes in high school.
In comparison, a graphing calculator has a huge advantage as a scientific calculator in the type of complex operations it can like calculus problems. The screen on a graphing calculator lets you visualize every part of the calculation and have a more intuitive workflow. Plus, you can copy and paste values from one problem to another, which is great for statistics, engineering, and physic problems.
Not only can a graphing calculator store numbers, but many models are also equipped with Wi-Fi allowing you to download programs and apps from the internet. The biggest benefit by far, though, is the large screen on the graphing calculator along with its sophisticated and complex calculation capabilities.
Common Graphing Calculator Features to Look For
Almost any student taking classes in higher-level mathematics, physics, or chemistry will find that there comes the point when it is almost essential that they own a graphing or programming calculator that can perform computations with much more power than basic scientific calculators. While teachers should be cautious to ensure that students still learn the conceptual ideas without relying on a calculator, there are times when using a calculator is inevitable, especially in this day and age, when the industry moves forward with more computerization.
Anyone who has researched different calculators will know that there is a wide range of brands to choose from, each with many different model names. It can be somewhat overwhelming to decide on a single model, especially with so many features to look out for. This guide aims to introduce some of the common features available on modern graphing calculators.
2nd (3rd) Functions
Typically, the buttons found on a graphing calculator will have two functions. You can use a 2nd function or SHIFT key to access the second function of each key. This allows fewer keys to be found on the calculator and creates confusion and cluttered, making it hard to read. Make sure you consider several models and find the one that works best for your needs.
Graphing Capabilities
Always make sure you have considered what you want the calculator to do before you choose a model. An engineer will probably require more capabilities than a student, so it’s important to consider the calculator’s abilities and match them to the applications. Also, think about the calculator’s ability to download programs and apps to progress with the user through several types of math and science classes.
Processor
The calculator’s processor is also a big consideration since it controls how fast the device will work. When used in a graphing calculator, the measurement of the processor’s speed is called Megahertz. A good rule of thumb is that the faster the processor, or the higher its Megahertz, the more immediate your decision-making can be at your job or on a test.
Screen Display
When considering the screen display, this is really just based on your personal preferences. If you are considering calculators with a monochrome screen, they all basically work the same way. But, when considering a graphing calculator, a larger screen or one that is colored can help in different applications. Remember that it really all depends on your specific wants and needs.
Battery Life
Typically, a graphing calculator uses batteries to operate. A rechargeable battery is usually the best choice if you know you will use the graphing calculator a lot.
Natural Math Display
This is probably one of the most searched calculator features among students looking to purchase a new calculator. While different brands use different names (e.g., Texas Instruments refers to it as “pretty print”), natural math display just means that the calculator screen will show expressions exactly as you would write them on a blackboard or piece of paper. You can use full-sized symbols for summation, differentiation, and integration. Fractions actually look like fractions, and gone are the days of trying to define a 9×9 matrix with only one line of text. For any student taking mathematics classes, this feature can be convenient. Even for the advanced student, it is still quite a luxury to have a natural math display as it makes checking over calculations much more efficient, and there is less chance of making errors.
3D Graphing
3D graphing ability is one of those features that may be essential to some people but not required for others; it really depends on which classes you plan on taking or what your research involves. A 3D graphing ability simply means that the graphing calculator can produce graphs of multivariable functions over the “x-y-z” space instead of only the Cartesian x-y plane. For anybody taking classes in multivariable calculus or linear algebra, the ability to make 3D graphs could come in very handy; however, for people taking elementary algebra or trigonometry, it may be one of those “take it or leave it” features—nice to have but not essential.
Computer Connectivity
Students often overlook a feature when purchasing their first graphing calculator is connecting to computers and other calculators via an electrical cable (i.e., USB). As calculator technology advances, there is an increasing similarity between the software on a calculator and the computer’s software. Some of the higher-end programmable calculators can actually run software programs and applications that have been developed for that model of calculator, and installing them generally requires transferring the program from a computer to the calculator. This is a great advancement in technology because students can have programs that will solve calculus, physics, linear algebra, chemistry, or any other subject much easier. For calculus, you could install a program that has a list of common integrals and derivatives; a chemistry student may find it handy to have a periodic table, and a physics student may find a program that has all of the equations of motion to be indispensable.
Computer Algebra System (CAS)
CAS is a relatively new feature on modern graphing calculators—it was not long ago that CAS capabilities were only available on complex computation software such as Mathematica or MATLAB. Basically, the CAS allows you to perform algebra on symbolic variables without giving a numeric meaning to each variable. For example, if you wanted to find an expression for the derivative of log(x), a calculator with a CAS could easily tell you that the answer is 1/x; however, any other ordinary calculator could only do it numerically and evaluate the derivative at a particular x value which may not be as useful. As another example, if you want to solve an equation, say “y = 6x + 2”, an ordinary calculator might solve one of the variables if you know the other’s value. Still, the CAS can re-arrange the equation with both variables unknown to give “x = (y-2)/6”. These two examples are relatively simple; however, the CAS facility can become indispensable for more complex calculations!
If you need to utilize a graphing calculator’s specific technology, it’s helpful to have all the essential information to make the right decision. Engineers might benefit from a more advanced display capable of visualizing regression models. If you choose a too basic calculator or too advanced, you could run into usability problems. Here are a few tips and reviews to help you find the best graphing calculator for your needs.

There are several comparable calculators for about the same (solid) price. The Casio FX-9860GII does what it has to do, has a clear keyboard and a clear display that is still easy to read in poor lighting conditions thanks to the handy backlight. The operation is very intuitive, so in most cases there is no need to refer to the manual provided. The calculator fits snugly in the hand and can easily be stored in a robust plastic cover. In short, a good calculator that won’t bother you.
For me the “Plus” model is an upgrade for my previous plane, the regular Texas Instruments TI-84. I am pleasantly surprised by the well thought-out further development of the product in this new device.Some pleasant advantages:
– the manageability/usability due to the smaller thickness of the device so that it fits better in the hand and weighs less.
– extremely bright and clear screen
– the colour display which gives an extra advantage over the drawings
– the simple charging of the device, without having to endure the eternal battle with batteries
If I really had to mention a negative point, it’s just the fact that the device gets ‘dirty’ quickly because of the glossy finish. It’s easy to see the slightest dirt on it.
But on this futility I will certainly not write this device off.
Top device !
After my TI-84 Plus broke down and it was no longer available, the TI-84 CE-T seemed a very logical choice to me.
I am especially happy that the interface is the same, which is of course useful if you have known the device for quite some time. Also taking lessons is easy as you don’t have to do anything special to be able to do it on your device.
Advantages are that you don’t have to walk around with a pack of batteries before an exam. The night before, just don’t hang your mobile phone on the charger and hang your calculator on it; because you can just use a USB charger to feed it again.
With the TI-84 Plus you could already distinguish graphs by displaying one thicker or in dotted lines, but with the CE-T you can choose a colour to distinguish them.
The only disadvantage is that the CE-T is a bit more fragile than the Plus. Not only because it is thinner (the Plus got its inspiration from Nokia), but also because the LCD screen is more sensitive to scratches, where the screen of the Plus was a bit deeper. So you have to pay attention, especially if you were used to the ‘Bump’ plus. The advantage is that my backpack can now be closed more easily because it is thinner.
The battery is very good. After a week of use every day for at least one and a half hours, I still see a full battery on my screen.
For the Plus I had a written program for discriminant and another one and this one can be perfectly transferred from Plus to CE-T with the link cable (included). The CE-T can now display even more than m’ Plus could.
Of course, the Amazon service also deserves a compliment, because the delivery time was perfectly respected.
When I bought my Texas Instruments 84+ I had little knowledge of mathematics, now many years, and a huge amount of exercises later we have become inseparable. Figuratively of course…
The nice thing about this device is that you have a nice overview of what you want to calculate. You can always review your operation and adjust it if necessary. This is impossible with most pocket calculators. This allows you to learn what you did wrong, adjust certain operations and see what suits you, and thus improve your understanding of mathematics.
For students, the device is certainly recommended because it has a long battery life, in combination with a solid design (which has proven its worth many times), and the interface of the device is very clear, so you can get away with it quickly.
The graphing calculator is very easy to use, for example to plot functions, determine intersections of your functions, minima and maxima, and so on….
Also useful are the apps that you can put on your calculator via the USB port. Although, as a student, I would strongly advise against it: yes, you can also put games on it, but this unfortunately creates quite a distraction.
The device is equipped with a USB port, with which you can exchange files between your computer and your TI-84+, or between two calculators. There is also an I/O port (input/output), which can be useful for IT specialists.
A disadvantage of this calculator is that the LCD screen consists of fairly large pixels, which sometimes causes confusion when studying your graphs, but the advantage is that your screen is easy to read from all angles. The device is also a bit heavier than a normal calculator, but I liked that just as much. The price tag is rather high, but since the device is really sturdy, on top of the 3 year warranty, I wouldn’t be deterred by that. It is also the best graphing calculator from Texas Instruments that is allowed at universities and colleges.
My conclusion is that this TI-84+ is definitely my favorite device, and once you have used this device, you will never want to go back.
This was a compulsory purchase from school. Of course a 2nd hand searched, but not found on time.
Via Amazon, the Casio FX-9860GII was delivered a day after ordering. You have to read the manual carefully to work with this machine and to extract what is inside.
So far it’s been great. Can be connected to a laptop, for example, and makes the most complicated calculations. The screen is good and easy to read.
After searching for a graphing calculator on the internet, I finally came up with the Casio FX-CG20 and it is highly recommended.
The calculator is very clear, easy to use and has a perfect display.
The menus are displayed as icons, it’s easy to understand and you hardly need to practice to work with this calculator.
The display is very clear, sharp and easy to read. The fact that it supports colours distinguishes it from other displays and is also a good reason to choose the FX-CG20.
The Fx-CG20 is highly recommended!
The delivery was also perfect, just like the next day in the house.
I bought the Texas Instruments TI-89 Titanium for a few classes in high school and it has lasted me well into college. I say it’s a great investment if you know you’ll be needing a nice calculator for the next three to five years. It is very compact and has a nice case to protect the screen and buttons from random wear and tear.
I have experience of using Casio FX-CG50.
My pluses are:
+ You can adjust the brightness of the display, so you don’t have a very bright screen when it’s dark.
+ You have a lot of options, you can even take notes.
+ You have caps on the bottom for extra grip, so it doesn’t slip away when you’re typing.
I had some drawbacks, like:
– The cover sometimes opens stiffly.
And in my opinion I don’t like the back, because it’s white. But for the rest, it’s a very comprehensive and user-friendly graphing calculator.
The FX-CG20 has a nice design and is very easy to navigate, the different options (menus) are shown in icons, this makes it clear and very easy to find your way around. You don’t have to practice using the calculator at all.
Also on the display is nothing to be criticized, the display is very bright, sharp and easy to read. The fact that it supports colours distinguishes it from other calculators and is a reason to choose the Casio FX-CG20.
There’s nothing I don’t like about this calculator.
The delivery was also perfect, just like the next day in the house.
Highly recommended!
I really like the TI-84 calculator because it really is a world of difference compared to the normal calculator. because you can do a lot more. (apart from being a graphing calculator), the speed of the calculator feels faster than another with an older version. The only thing that really bothers me is opening the cover. It’s a lot of fiddling to open the cover. And especially if you are careful it feels like you have to put so much force on it that it almost breaks down. And I also think that the display could have had a slightly higher resolution for this price.
.. although the word “calculator” doesn’t completely cover the load anymore. This is just a small miracle, a kind of pocket-sized Einstein, I’d say. In addition to its handy size, its standard cover plate is immediately noticeable that this Texas T84 is full of functionalities and that you really need to take some time to read the manual (really that saves a lot of frustration).
I bought this Texas 84 for my daughter for her exams, but now I have it in my possession for 14 days and use it more than she will ever need… think we’ll only buy one more 🙂
When my TI84+ died, I ordered this upgrade. No more hassle changing batteries for an exam, just charging and going. Color screen is a nice extra, makes it just a little newer. The functions are all the same as on the old TI84+, so it gives you the familiar feeling. Just feels a bit more fragile and sensitive to scratches than its predecessor.
I use the Casio FX-CG20 graphing calculator for my study and I am very happy with it. Although at first it is difficult to find all the functions you need, without going through the entire manual, it is a very practical graphing calculator. The screen is very sharp and very clear, especially because of the color screen where you can display graphs and tables with different colors. So far, I’ve noticed that the screen scratches pretty quickly, I’ve been paying attention to this because I’ve read this problem in other reviews as well. So even with careful use you will somehow get scratches on your screen. The scratches I have are not annoying or deep but only when you pay attention to them you will see them, so it is not really a drama during use. Apart from the small scratches, I can recommend this device to anyone!
