Mathomatic is a free, portable, general-purpose Computer Algebra System (CAS)
that can automatically solve, differentiate, simplify, combine, and compare
algebraic equations, perform standard, complex number, modular, and polynomial
arithmetic, etc. It does some calculus and is very easy to learn and use.
Plotting expressions with gnuplot is also supported. This package
is complete, including Mathomatic, the Prime Number Tools, m4 Mathomatic,
and all documentation.
