Moodle has an "algebra filter" which can display mathematical expressions as if they were typeset. The filter is included in the standard Moodle packages but the administrator must activate it before you can use it.

The filter (see http://cvs.moodle.org/moodle/filter/algebra/ ) uses algebra2tex.pl, a perl script (and its associated perl module, AlgParser.pm) to parse text expressions delimited by double@ signs as tokens (though the tokens employed can be tweaked manually.)
While many have argued that the algebra filter is easy to use, there is apparently no Moodle reference on its "grammar" or "syntax". Research in to Webworks produced these two links for using webworks text expressions (the first one is arguably replaced by the second):
