Mathomatic is designed to be as general and easy to use as possible.
The software implements most of the rules of algebra for addition,
subtraction, multiplication, division, modulo division, and all forms
of exponentiation. All arithmetic is double precision floating point
with up to 14 decimal digits accuracy.

Mathomatic can symbolically combine and solve equations containing many 
variables, completely simplify and compare expressions and equations, do 
simple calculus transformations and series, perform standard, complex 
number, and polynomial arithmetic, generate optimized C, Java, and Python 
language code from simplified equations, carry out quick calculations, and 
much more. Plotting with gnuplot is also supported. Not implemented in 
Mathomatic are named functions, arbitrary-precision arithmetic, and
matrices.
