Casio FX-260 Solar Scientific Calculator

This is the only calculator that students are allowed to use during the GED Mathematics Test.  In fact, the test administrators provide each student with one of these calculators when he or she sits down to take the test.  An exceptional value, the Casio^® fx-260 is really a little powerhouse of a scientific calculator.  It performs some 144 distinct mathematical functions (including many used in higher-level mathematics like trigonometry, statistics, and pre-calculus).  It features an easy-to-read LCD display, a large, color-coded keyboard, a backspace key for fixing entry mistakes (!), and a convenient, slide-on hard case.
