MathJax AsciiMath

 AsciiMath is a text-based mathematics format developed by Peter Jipsen, and available as ASCIIMathML.js and in several related forms. Its syntax is a simple algebraic style that makes it easy to type mathematics in a natural way and convert it into MathML. Page authors were using ASCIIMathML.js in conjunction with MathJax, which required some coordination of the two. In version 2.0, MathJax included a new input jax for AsciiMath notation. See the MathJax Documentation for more details.
