# Maxima

**GNU Maxima** is a

free computer algebra system, written in

Lisp and released under the

GNU General Public License. It is based on an early version of

Macsyma developed at MIT with funding from the

United States Department of Energy. Maxima was maintained by

Bill Schelter from

1982 until his death in

2001. It is now maintained by an independent group of users and developers.

The GNU TeXmacs mathematical editor program can be used to provide an interactive graphical user interface for Maxima.
