Mathomatic, a free computer algebra system

Welcome to The Home of Mathomatic

Mathomatic is a portable, general-purpose computer algebra system (CAS) written entirely in the C programming language. It is free and open source software (FOSS), published under the GNU Lesser General Public License (LGPL version 2.1). The software does automatic manipulations and calculations of mixed symbolic/numeric mathematical expressions, allowing quick and easy solving, differentiating, simplifying, etc. of elementary algebra.

This is an easy to use text mode application and library that compiles and runs under any operating system with a C compiler. The mathematical results should always be correct, simple, and beautiful; if not, please report it on the Mathomatic project site on Launchpad.net, or you can email the chief maintainer for a quick response.

The current version number is "15.1.5", released July 20, 2010; download it or view the changelog.

New! - Mathomatic is now also available online with a web interface.
