The scientific calculator is a fundamental tool for both high school and university students.
Selecting the correct calculator is a task to which you must dedicate the necessary time. Do not buy the first one you see.
Investigate what they need and eventually what you need from a scientific calculator. Consult, compare and draw your own conclusions.
The idea of this article is to know which are the most sought after models in the market.
We are going to see scientific calculators of different brands and we will go from the most basic to the most complex
Casio FX-82MS
The Casio FX-82MS is the most used of all scientific calculators for students.
Its fame is because it is reliable, cheap, easy to use and standardized. As there are many students who have it, they are passing the tips on how to use it.
When you do not know how to do certain operation or procedure with this calculator, it is usually easy to find out
Hewlett Packard 10s Plus (NW276AA)
The second model that we will know about the scientific calculator is the HP 10s Plus from Hewlett Packard. A similar model to the HP 10s we eleven talked about in Liberated Minds.
This calculator comes with a two-line display with VPAM system, which allows expressions to be assembled visually easily.
You can perform the basic operations and also work with fractions, sexagesimal system, logarithms, powers and roots. It includes 240 functions among which the trigonometric ones stand out, some of probability and statistics (mean, standard deviation and variance) and combinatorial (permutations, combinations and factorials).
Casio FX-82ES Plus
We could consider the Casio FX-82ES Plus as the older sister of the FX-82MS. The arrangement of the keys is similar and also includes a removable cover.
However, the screen is Natural-VPAM and is larger, allowing more lines to enter. This allows, for example, not having to enter fractions in a single line.
Casio FX-991ES Plus
Above the FX-82ES Plus, we find the Casio FX-991ES Plus. This is another calculator with Natural VPAM display, which allows writing in several lines.
In addition to supporting all the basic functions that her younger sisters, this sum 417 functions in total. It incorporates a solar cell and works with a single LR-44 battery.
Casio FX-991 SPX II
This is one of Casio’s newest calculators. The Classwizz appeared in 2015 and settled among the best and most modern in the market.
You could say that it is a small computer in a calculator. The display is LCD with high resolution of 63 x 192 pixels. This allows you to display menus with graphics.
As for benefits, in addition to all that we saw from the other calculators of Casio, this includes 576 functions. It works with complex numbers and can solve systems of equations of up to 4 unknowns.
As for vector algebra, it is designed to work with vectors. Calculated scalar, vector product, angle between vectors and normalization. Work with arrays of up to 4 x 4. You can calculate determinants and invest matrices. Those who study algebra will know that these functions with arrays are a great advantage.
