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.

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.

Testimonials

I feel like Casio should be paying me for the amount of talking I do about this calculator. First off, I've owned the fx-115ES for about 2 years now and love it. I love it so much that I've not only recommended to almost anyone who will listen to me, but bought it for two of my friends for their birthdays. When I found out there was a PLUS version of this calculator I was more excited than any one person should be about a calculator, and I didn't even know what the plus stood for. Turns out it's a bunch of small things that us math majors really appreciate; lines over repeating decimals, gcd and lcm, remainders (for modular arithmetic, and a bit more memory than its predecessor. BUT IT'S PREDECESSOR WAS ALREADY AMAZING, so basically this calculator is amazing plus.

If you require a handy scientific calculator to arrive at numerical results quickly, look no further than this this little gem. Everything you need to do the most common types of calculations is right at your fingertips in an intuitive and convenient arrangement. This is not a computer algebra system or equation visualization package, it is designed for producing real results for discrete computations.

As an engineer who also owns graphing calculators, I really appreciate this little marvel. This is a compact, lightweight, and inexpensive unit that you can take with you anywhere. A handy sidekick for CAD to solve for angles and various things. The finite integration is well done and easy to use.

The features of this calculator are legion. It deserves my highest recommendation.
