I bought this calculator for use in my precalc class at the recommendation of my instructor. This thing kicks ass. The formula mode lifesaving! Do yourself a favor and watch a couple YouTube videos to get an idea for what this thing is really capable of so that you can maximize its effectiveness for you.
Are you a high school or college student, an engineer or just a mathematics teacher who is all confused as to which Scientific calculator to choose from especially when you have so many options available and at the same time making sure it is easy on your pocket. Then Casio’s fx 115ES Plus is your answer.
Why Casio fx 115ES Plus?
Casio markets itself as a simple to use and affordable alternative to their competitors, and that once again turns out to be true and has been designed and engineered for easy operation at any level. Weighing just at 3.35 ounces, this calculator won’t add any burden to your backpack. Its keys are plastic and it comes with a hard cover for safekeeping. 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.
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.
In case you are looking for something much more powerful like a graphical calculator which can accomplish a lot more then we would suggest the following calculators:
