DragMath is a free "drag and drop" equation editor. It is a Java applet which can simply run within a web browser on most computers.
The editor lets users build up mathematical expressions in a traditional two dimensional way, and then output the results in a correctly formed syntax. This is not so easy: mathematical notation contains some ambiguities. Still, we appear to be stuck with traditional notation for the foreseeable future, see for example this article for some comments on notation. This gives some idea of the design of DragMath.
The supplied output formats are MathML, LaTeX, Maple, Maxima. It is also possible to convert the expression to almost any user defined style by creating an XML file with the correct syntax data in it.
Although mathematics is less dependent on language than many things, the applet loads a language file which makes it possible to translate DragMath into other languages. DragMath has currently been translated into: Catalan, Czech, Dutch, English, French, German, Norwegian, Polish, Portuguese (Brazilian), Russian, Spanish and Swedish.
DragMath makes use of the MathTran service to automatically convert expressions to images.
