You may wonder why there are some people in your class who often score high in math exams or any other tests involving computations. Well, besides the fact that there are those who really possess great analytical skill, there are some who rely on genius calculators!
Equations in Algebra
In this article, I will show you how you can make better use of your CASIO calculator (i.e. solving equations for x) in 3 easy steps.
Calculators that has Solving Capacity
Unfortunately, not all Casio Calculators have the capacity to perform algorithms on equations. In other words, not all calculator has the function of solving for x.
In my case, I needed to purchase a new one just to get an edge in my Economic Statistics subject. Was it worth it? Well, yes! I got a considerably higher mark with the help of my amazing calculator. It was very useful in reducing careless errors. Plus, I was also able to use it in my other subjects as well like Business Math and Accounting.

The price of this calculator certainly doesn’t reflect its enormous range of possibilities.
The fx-115ES Plus is intuitive and easy to use as you progress through your day to day work. The Casio Scientific Calculator FX-115ES PLUS offers the newest trend in scientific calculators: the “natural textbook” look. Inputting complicated equations and reading outputs is made easier with this function because of the way the numbers are organized on the screen.

For example, while solving equations which involves fractions the ability of the calculator to depict the fractions as you would write on a paper – a numerator directly above a horizontal line and a denominator beneath helps tremendously since your mind is accustomed to viewing equations and examples from written text. Also with just a simple press of a button you can toggle from fraction to decimal and vice versa.
History gone! – a drawback?
Even though its an amazing calculator there is one major concern which is reported by customers who are otherwise very satisfied – the history issue. Yes that’s right, the history if wiped when ON button is pressed or when switching between the modes. Let’s say for example you were in middle of solving a complex equations and after inputting all the required details you got the result but you decided to take a beak but as soon as you return back VOILA ! everything is vanished that’s because the calculator automatically shuts off after a couple of idle minutes, which is great for saving power but will also erase everything.
Summary
I have tried many other calculators. You will not find a cheaper entry level scientific calculator than the FX-115ES PLUS from a quality name like Casio which provides a tremendous amount of features for the price. If you need to save a few dollars, it’s an excellent choice.

Casio V.P.A.M. calculators are scientific calculators made by Casio which use Casio's Visually Perfect Algebraic Method (V.P.A.M.), Natural Display or Natural V.P.A.M. input methods.
V.P.A.M. is an infix system for entering mathematical expressions, used by Casio in most of its current scientific calculators. In the infix notation the precedence of mathematical operators is taken into account. According to Casio, in V.P.A.M. calculations can be input exactly as they are normally written. Functions, operators and symbols are shown on the calculator display and calculations are performed according to operator precedence.
History[edit]
The V.P.A.M. name was first introduced in 1994 with the introduction of the fx-991S scientific calculator in Japan. In 1998, the Casio fx-991W model used a two-tier (multi-line) display and the system was termed as S-V.P.A.M. (Super V.P.A.M.). The model featured a 5x6-dot LCD matrix cells on the top line of the screen and a 7-segment LCD on the bottom line of the screen that had been used in Casio fx-4500P programmable calculators.[1] The S-V.P.A.M. system was also used in the other W series models and also the MS series of calculators that followed. V.P.A.M. is similar to the Direct Algebraic Logic (D.A.L.) used by Sharp in some of their scientific calculators.
The fx-82ES introduced by Casio in 2004 was the first calculator to incorporate the Natural Textbook Display (or Natural Display) system. It allowed the display of expressions of fractions, exponents, logarithms, powers and square roots etc. as they are written in a standard textbook. Natural Display uses natural representation of mathematical expressions and formulas through a 96 × 31 dot matrixLCD display. Casio uses the term Natural V.P.A.M. for the fx-ES Plus series of calculators which are the upgraded version of the fx-ES series.
In early 2015, Casio introduced a new line of calculators called CLASSWIZ for different markets, featuring a high resolution (192 × 63) dot matrix Natural Textbook Display and incorporating spreadsheet functions in some models. This series of calculators is called the fx-EX series and it succeeds the fx-ES Plus series of calculators.
