Casio Classwiz FX-991EX Scientific Calculator

As exam boards abandon the archaic practice of handing out printed statistical tables, the Casio fx-991EX Classwiz has become the baseline calculator for students who are too mean or too poor to invest in a good graphics display calculator. However, for the price, this is a truly excellent calculator that offers a multitude of features. But, to get the best out of it, you need to learn how to use it effectively. It’s very unlikely that your school will teach you how to do this, which is why this book has been written. With over 400 screen shots, and all the accompanying keystrokes, you won’t be left guessing how to do something. Because, learning how to use this calculator well will definitely improve your exam grades.
