Algebrator
Algebrator (also called Softmath) is a computer algebra system (CAS), which was developed in the late 1990s by Neven Jurkovic of Softmath, San Antonio, Texas. This is a CAS specifically geared towards algebra education. Beside the computation results, it shows step by step the solution process and context sensitive explanations.
