Touch-screen calculator with symbolic computation 

The fx-CG500 PRIZM® CAS brings touchscreen technology to the graphing calculator. This CAS calculator's extra-large screen allows for more complete and detailed mathematical exploration. Its drag-and-drop functionality enables users to quickly and intuitively pull information from one representation to another. Incorporating CASIO's standard Natural Textbook Display, convenient drop-down menus, a handy soft keyboard, and CAS (Computer Algebra System), the fx-CG500 is a powerhouse computational machine.

The fx-CG500 includes a stylus, stylus compartment, and a slide-on protective hard cover.

Approved for the SAT® and AP® tests.

The fx-CG500 CAS is Casio's premier handheld computational device, supporting a three-digit exponent and the expansion, simplification, and computation of symbolic math. The CG500 supports an suite of math apps and modes including advanced three-dimensional graph plotting and analysis.

To help facilitate easier math input, the fx-CG500 features both a "hard" (physical) keypad and "soft keys" (a tabular keypad that appears on screen). Soft keys can be selected using the directional pad, by pressing the screen with a finger, or by using the supplied stylus.

Due to the fx-CG500's limited exam acceptance and advanced set of features, Casio recommends this calculator for graduate studies and post-graduate research purposes. For High School level mathematics, please see the fx-CG50 PRIZM.
