Mathematical Expressions Editor

Formulator Mathml Weaver is a mathematical expressions editor that
allows the user to create, and print, mathematical equations through simple
point-n-click techniques. It features extensive symbols (separated
into Presentation & Content types), expressions also displayed as
tree/text/XHTML, virtually unlimited undo/redo, 192-page PDF Helpfile, and
more. This is not a calculator but a tool to accurately display
mathematical equations so they can be printed or, in the case of XHTML, exported.
Create your mathematical model and then print it out, turn it into a
graphic or XML file, or share it with others as an XHTML file. The number
of symbols offered through Formulator Mathml Weaver is excellent, and
there is even a massive Helpfile if you are unsure what to do. We were
most impressed with Formulator Mathml Weaver and are happy to recommend
it.
