 technologies into a single, definitive, math-on-the-web platform supporting

 It requires no setup on the part of the user (no plugins to download or
 software to install), so the page author can write web documents that include
 mathematics and be confident that users will be able to view it naturally and
 easily. Simply include MathJax and some mathematics in a web page, and MathJax
 will do the rest.
