Mathics—to be pronounced like “Mathematics” without the “emat”—is a general-purpose computer algebra system (CAS). It is meant to be a free, light-weight alternative to Mathematica®. It is free both as in “free beer” and as in “freedom”. There is an online interface at, but it is also possible to run Mathics locally.

The programming language of Mathics is meant to resemble Wolfram's famous Mathematica® as much as possible. However, Mathics is in no way affiliated or supported by Wolfram. Mathics will probably never have the power to compete with Mathematica® in industrial applications; yet, it might be an interesting alternative for educational purposes.
