Casio FX-991 CW ClassWiz® Advanced Scientific
Item # CS-FX991CW

Casio’s ClassWiz® Advanced Scientific is the latest enhancement to the scientific calculator. With an all-new quadruple graded LCD display, users will be able to easily find their cursor while writing and modifying expressions.


The ClassWiz features circular, convex buttons that are appropriately spaced to prevent mis-keying information, and the button labels now feature glyphic representations of the functions they perform. The hard plastic case features an etched edge surface to prevent slipping in the hand.


The ClassWiz can store and recall up to nine variables which can contain integers, computations, and functions. The variables will persist in the calculator's memory between sessions. All of the calculator's functions can be accessed through the convenient Math Catalog. The Math Catalog also hosts 47 scientific constants and 40 measurement conversions. By partnering the ClassWiz with an internet-capable mobile device, solutions can be graphed and visualized through ClassPad.net by scanning a QR code on the calculator's screen.
