If c² = a² + b², then what do a, b, and c equal? Mathomatic is a small Computer Algebra System (CAS) that works like an algebraic calculator. Expressions and equations are entered in standard algebraic (infix) notation. Operations are performed on them by entering simple English commands.

Mathomatic is designed to be as general and easy to use as possible, and as such, has no programming capability. The software implements most of the rules of algebra for addition (+), subtraction (−), multiplication (*), division (/), modulo division (%), and all forms of exponentiation (^ or **). All arithmetic is double precision floating point with up to 14 decimal digits accuracy.

Mathomatic can symbolically:

• combine and solve equations;
• completely simplify and compare expressions and equations;
• do calculus transformations (derivative, Taylor series, and polynomial integration);
• do standard, complex number, and polynomial arithmetic;
• generate optimized C, Java, and Python language code from simplified equations;
• do quick calculations, colorize expressions, etc.

Mathematical functions (such as f(x) and log(x)), plotting, and arbitrary precision arithmetic are not implemented in Mathomatic; these capabilities are available in a larger, full-featured CAS like Maxima or Sympy.

Examples:

• Some simple examples
• Some non-trivial simplifications
• Combining, solving, and simplifying a system of linear equations
• Combining, solving, and simplifying a system of non-linear equations (same method)
• A snapshot of Mathomatic running within xterm (a terminal emulator that runs under X-Windows)
• A picture of Mathomatic ported to the Nintendo DS gaming console running the DSLinux operating system
