What is MathML? MathML (Mathematical Markup Language) is an
industry standard adopted by the World Wide Web Consortium (W3C)
as the approved way of expressing math on the web. Like the more
familiar HyperText Markup Language (HTML), which sets the
standard for web browsers to display literary text, MathML is an
international open standard for encoding math content. MathML is
needed because HTML has no means of marking up mathematical
expressions. Using MathML provides the highest level of
accessibility to math within digital documents. Before the
advent of MathML, web authors often resorted to inserting
graphical images, basically digital "pictures" of equations
taken from other software products, into their documents. Such a
practice is problematic because graphical images are inherently
inaccessible. Although alternate text descriptions (commonly in
the form of "alt tags") can be added to these images, this
approach has drawbacks because text does not always provide true
comparable access to information fou
