Analysis of the best scientific calculators

Texas Instruments-Nspire™ CX CAS

(Our recommendation)

No one wants a graphing calculator with a screen that looks like something straight out of the ’80s. What you will want one that has a sharp screen, of great quality, and that has a performance similar to a mobile and the TI-Nspire CX CAS is its strong point and nails it with the quality of the screen being the best of the 3 in terms of screen viewing.
Texas Instruments TI Nspire Calculator
It must be said that color-coded tabs on the screen and animated graphics really improve the user experience.
In addition, this scientific calculator features advanced functionality for math, science, engineering, and architecture. You can even import digital images and place graphs and equations on them, supporting images in .jpg, .jpeg, .bmp, and .png formats.
It is also possible to create documents and pages and store them as you would with a computer. Even more, it has the ability to enter equations into the proper notation, with superscript and subscript.
The‘Computer Algebra System’(CAS) functionality of the graphing calculator allows you to manipulate equations and solve any variable within the equation. For example, if you are a student and you have the subjects of Physics and / or Chemistry you will find this functionality very useful because it helps you discover the theory that drives the equations.
The other thing I love about this calculator is that it’s fast.Some older models (including the predecessor of this one) calculated too slowly when you threw complex polynomials at them.
The processing speeds if it is slow surely can despair if you are one of those people who when the computer is slow click a thousand times to go faster, hehehehe and …. if you are performing a complex calculation during any of your exams you will need until the last extra second. Well, do not worry because with this calculator everything will be very fluid 😉
And to finish the first analysis of the “best scientific calculators” we end up saying that the battery life is very good in this calculator and you will not have to be aware of recharging it every two by three, since the manufacturer tells us that the rechargeable battery can last up to two weeks.💪🔋🔋🔋

Buyer Reviews

It has everything you could ask of a graphing calculator with CAS, including the possibility of programming. It includes two cables: one for connection to another Nspire series calculator, and another USB for connection to the computer, both for charging from the USB port and for data transfer with the PC application. Keep in mind that the pack does not include this software, but a card with the address for the download and the activation key of the same. Also, on the IT page are available for download abundant documentation, other software (including updating the firmware of the calculator) and a large number of documents with lessons from the most varied subjects (algebra, calculus, geometry, statistics, etc.)

HP Prime G2 Calculator

(Best seller and best quality/price)

From experience, I have to say that HP is one of the best scientific calculators and easy to handle, as long as you have had some previous knowledge, since it has enough functions without forgetting that it is very powerful.

Best HP Prime Scientific Calculator
The good thing about this calculator, which is manufactured by a big brand like HP, being a device that will last you years because there is a great team behind. Our first calculator that we have shown you in the image takes 20 years and is still perfect.
The HP Prime G2 calculator is the best-selling calculator (for something it will be) and according to quality / price it is the best according to our criteria with unique features.
If you decide on this calculator we must indicate that the level of learning is intermediate, it is also sophisticated enough for users who are doing a university career or if they already work as engineers, architects …

| Linear algebra like quantum mechanics is a a cake with this calculator!

It works like a normal graphing calculator, but is full of functions such as the Computer Algebra System (CAS) being able to do complex mathematics that include not only functions and numbers, but also symbols (for example, variables, definite and indefinite integrals, etc.).

They can make advanced 2D and 3D graphics as well as use the ‘HP Solve’ application, which allows you to solve equations of various variables step by step.

This calculator can solve algebraic equations and simplify expressions. It has many mathematical commands that do not fit on the keyboard, but you can access them through the menu (as the other calculators I have to say).

It features a high-resolution multi-touch color display.and a touchscreen interface that makes it much easier to use. Its functions include charts, lists, matrices, fraction templates, and many others.
Many functions are aimed at students and teachers, for example, numerous educational applications (trigonometric and quadratic equation solvers, dynamic geometry, a triangle solver, etc.).
It also has a wireless system to distribute surveys and questionnaires, put calculators in exam mode and take screenshots or the DataStreamer Application for data collection.

An excellent product for students and professionals of technical modules and degrees, as well as for professionals. Multiple functions, comfortable, restrained size… a first class product” – Pablo Martino

Casio Classpad FX-cp400

(Better screen and ease of programming)

Best Calculators for Engineers 2020

The scientific calculator fx-CP400 is the best screen in terms of size since it counts to be XXL touch LCD of 4.8 inches providing clearer images of mathematical data for students, engineers, architects …
Best casio scientific calculator
Thanks to this clarity, it is easier to understand the equations and graphs, since the calculator can display both at the same time. In addition, at the touch of a button, the fx-CP400 can switch from a portrait view to a horizontal view (landscape mode), which is convenient for displaying long mathematical formulas/expressions on a single line.
| The LCD screen of is the largest of the 3 calculators and is its strong point
As a CAS calculator (Computer AlgebraSystem),like the other calculators, it comes with advanced calculation capabilities being able to work with variables, solve limits or even systems of equations, derive, calculate vectors, matrices, the Fourier Transformation …
We again indicate that thanks to its large touch screen it is possible to drag and drop equations directly to graph it or use the calculator in landscape mode to enter, show formulas or larger mathematical expressions.
In Graph & Table it is possible to use real images as a graphic background but these images use a specific format (* .c2p).
There are also other functions such as Diff-Eq Graph, Spreedsheet, Statistics, , Num-Solver, Conics, Geometry and Financial, which makes the fx-CP400 not only a calculator suitable for students of algebra but also for students of finance or to help learn geometry, statistics…
In mathematics, everything is connected!!! 😆
As far as programming is concerned, the calculator comes with an easy-to-learn built-in basic language where it has commands related mainly to color.
Although it is not very fast,it is possible to create games and programs with it.
In short, it is a great educational tool and for all those people who are used to using penless touch screens on phones and / or tablets (like me), you will find that the pen is an even more practical and elegant way to use the calculator combined with your keyboard.
Another good aspect is that the calculator works as a USB storage device when connected to the computer. It is possible to connect the calculator to the laptop anywhere (home, school, university, office…) without any additional software on all systems (Mac, Windows, Linux…).
