Simple Equation makes it simple to put equations on the Web. Simple Equation project does not bother the user with the layout of the equation; it just displays it. The focus is on being simple to use.

One of the biggest obstacles to using mathematical expressions on the web is that the user currently needs to worry about layout. Web users should not have to learn a layout engine.

The class is built as a recursive parser. It is pretty easy to add operations to the parser, but it will not scale to a huge set of operations. That is OK, we want to keep things simple. At some point a layout engine may be required for a complexity level. This is not a layout engine.

Currently, only graphical output is generated, but it is hoped that MathML output can be generated automatically if the browser supports it instead of the graphic.

· Freetype

· gd

· PHP (Version 4 branch)

· Bar and hat functions were added.
