I am a Computer Science student and use this calculator in Linear Algebra, Discreet Math, Calculus (not as good as a graphing calculator for calc), and Number Systems (does conversions between base 16, 10, 8, and 2). It was particularly useful in Linear Algebra for all of its mtrix operations, and equation solver. What I like most about it is the "natural textbook display" that lets me set up equations the same way that I do on paper and that helps me eliminate careless errors with parentheses that I would normally use on my graphing calculator. My only complaint is after I set up an equation and I want to go back and edit it, the "left" and "right" buttons move the cursor slowly. However, it is an AMAZING calculator, especially for the price.

I have used Casio calculators for many years and prefer them over TI and HP. I gave this one 3 stars because the display is not easily readable in a desk top lighting situation. Get it away from the light even 10" and you either can not read the display or you will struggle.
They used a similar display on their first graphing calculator many years ago (own it) and it had the same poor qualities. I am at a loss to understand why they used it again.
Still, I would recommend it for anyone doing science (I use it for chemistry), math or even computer software (hex, octal, etc., conversions).
It has features I have not learned how to use that I'm sure I will find useful, like a table of scientific constants.

Great Calculator

Comments about Casio® FX-115ES PLUS Scientific Calculator:

I teach a number of courses where this economical and very effective calculator is recommended. You cannot beat it for the 18 dollars or so it costs. The conversion tables, log functions and calculus operators are very easy to access. I cannot recommend it more.

        Comments about Casio® FX-115ES PLUS Scientific Calculator:

        I was tired of Texas Instruments calculators eating batteries. I've used various TI calculators from as far back as the 70's when slide rule math was still taught in community college. This Casio is far better and even has a solar charger integrated in it. I thought I had to spend megabucks for an HP or high end TI but looked at the Casio and it had everything I need as a practicing engineer. Far better design, way easier to use and worlds better than anything I've had from TI (have had them for 30 years). I wish I switched earlier.
