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.

        I have struggled with Math off and on over the years. Now I'm in college and I love it!! My school offers tutoring and the the professor that tutors said to get this calculator-none other. Using this model does not cripple me from understanding the concepts, it enpowers me. I go thru the lecture, notes, exercises, homework, and quizzes. When I get to the midterm, other tests and next chapter-I comprehend and actually get it. That includes being able to check myself and get it right. I will be taking more and more math because I can build on a solid foundation and not feel lost. I keep this calculator with me always. There is no equation that I can not perform with it. Really appreciate the neat case cover.
