Calc++ (Lite) is a freely available calculator capable of performing complex mathematic operations including basic calculation, trigonometric calculations, and logarithmic calculations. The calculator also supports variable entry and will attempt to reduce equations entered into a simpler form.

This version is the "lite" version and doesn't support calculus based options such as derivation. If you wish to use these features, you can download the Calc++ (Full) Version on the Android Market.
