Yacas -Yet Another Computer Algebra System (Free Software Foundation).
Yacas is a computer algebra system (CAS) which has been in development since the beginning of 1999. The goal was to make a small system that allows to easily prototype and research symbolic mathematics algorithms. A secondary future goal is to evolve Yacas into a full-blown general purpose CAS.
