Click on Manage Tools
Click on the Manage Tools tab.
Select the check box to enable MathJax.
Below the Selected Tools list, check the box to Enable MathJax for automatic rendering of LaTex and AsciiMath in this site.

Enter LaTeX equation in rich text editor.
Insert "$$" before and after mathematical equation to set it apart from the rest of the text. Math equations are editable in the edit screen of the tool, but will display as equation in preview and student view.
