MathML is intended to facilitate the use and re-use of mathematical and scientific content on the Web, and for other applications such as computer algebra systems, print typesetting, and voice synthesis. MathML can be used to encode both the presentation of mathematical notation for high-quality visual display, and mathematical content, for applications where the semantics plays more of a key role such as scientific software or voice synthesis. The MathML Specification is quite long, complex and technical. To make it easier to get started with MathML, the following course emphasizes the main ideas with graphics and lots of examples.
