Definition
- MathML is about encoding the structure of mathematical expressions so that they can be displayed, manipulated and shared over the World Wide Web. A carefully encoded MathML expression can be evaluated in a computer algebra system, rendered in a Web browser, edited in your word processor, and printed on your laser printer.
The language
Hand-editing MathML is quite difficult. There are 30 MathML presentation elements (e.g. fractions), with about 50 attributes and around 100 elemens for content markup (e.g. operations such as + and functions). These elements are for encoding mathematical notation. Most elements represent templates or patterns for laying out subexpressions.
Integration with XHTML
MathML as extra vocabulary in XHTML
If your browser supports XHTML and MathML a simple example would look like this:
<?xml version="1.0"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN"
"http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd" >
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:math="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <head> <title>XTHML with MATHML</title> </head>

<p> <b>Corollary 2</b> [Contractive Sequence Theorem] <em>If
<math xmlns='http://www.w3.org/1998/Math/MathML'><mo>(</mo><msub><mi>x</mi> <mi>n</mi></msub><mo>)</mo></math> is a sequence, for which there is a number <math xmlns='http://www.w3.org/1998/Math/MathML'><mi>C</mi><mi><</mi><mn>1</mn></math> such
