HTML Editor: Graphical Equation

This is a visual editor that allows you to create mathematical and chemical expressions, using either your keyboard or a set of icons. This tool is good for new users and does most of the formatting work for you. To access it select the Equation button on the toolbar and then select  Graphical Equations.

In the window that opens, you can select from any of 10 tabs to build your expression. 

Tip: We recommend building the structure of your equation first, and then adding the numbers and inline notations second.

Depending upon the expression you wish to create, you may have to mix and match characters, symbols, and operators on different tabs.

Note: If you cannot find an icon, click on any of the Expand arrows to open a dropdown menu with more options.

By default, the contextual tab is empty until you need it.

When you place your cursor somewhere in an expression that has extra settings, those settings will appear in the contextual tab. For example, when you create a matrix, and then place your cursor somewhere in that matrix, you will get options in the contextual tab to add lines, alignment, spacing and other formatting to your table.
