The Equation Editor is accessible within the HTML Editor, which enables users to insert mathematical and statistical equations into an HTML page. It supports the input of MathML and LaTeX, as well as a graphical editor where you can visually create equations. Depending on your org settings, you may not have access to all input methods.
MathML is a standard adopted by the World Wide Web Consortium (W3C). It uses XML to describe mathematical notation by capturing both its structure and content. This enables MathML to support visual display and assistive technology access.
As a standard, Learning Environment stores and displays all equations in the MathML format, regardless of the format you use to enter equations. Learning Environment uses MathJax JavaScript engine to display MathML equations. While Firefox enables MathJax to render math in native MathML, MathJax will render math as HTML and CSS in other browsers which currently do not support native MathML.

LaTeX is a typesetting system based on TeX. It provides a text syntax for complex mathematical formulae. Learning Environment stores equations entered in LaTeX format as MathML to ensure consistency and accessibility.
The Graphical Editor is a Javabased application that features a tool bar equipped with a selection of buttons. This tool bar provides the necessary elements to construct your equations quickly and easily. Each button in the Equation Editor tool bar opens a palette of related mathematical symbols.
