- MathAction is an over-the-web graphical wiki-based interface for Axiom, Reduce and Maxima.
- MathAction provides MATHematical interACTION and collaboration using LaTeX?.
- On MathAction you can try out Computer Algebra Systems online.
- MathAction is based on LatexWiki - an extension of ZWiki.
- You can comment on the content or edit MathAction pages.
- You can enter mathematics using LaTeX?, Axiom commands, Reduce commands and and Maxima commands. The result as displayed as properly formatted mathematics.
- You can subscribe to the whole web site or to any page so that you will be notifed by email of new posting by other people.
- The Axiom MathAction wiki can also receive email and operates like a mailing list.

Yes, but really what is it good for ? In addition to the usual Zwiki features, MathAction currently supports these mathematical tools:

- AXIOM
Axiom is a computer algebra system. It is useful for research and development of mathematical algorithms for which it defines a strongly typed, mathematically correct type hierarchy.

- REDUCE
is a general-purpose computer algebra system geared towards the solution of large scale formal problems in mathematics, science and engineering. REDUCE offers a number of powerful operators which often give an immediate answer to a given problem, e.g. solving a linear equation system or computing a determinant (with symbolic entries, of course).

- MAXIMA
Maxima is a free computer algebra system, a GPL variant of Macsyma (which was the first comprehensive symbolic mathematics system and one of the earliest expert systems; many of its ideas were later adopted by Mathematica, Maple, and other systems.)

as well as:

- Noweb pamphlet format
Supports noweb-style literate programming, generating multi-format documentation and source code from a single wiki page.

- LatexWiki
- LaTeX? markup in wiki pages, used by the above.
- TouchGraph
A java applet for graphical navigation of the wiki.
