You can insert two kinds of equations: inline and figure.
To insert an inline equation, click the (Equations) toolbar button , and fill in the Insert Equation dialog box:
Figure 1: The Insert Equation Dialog – Inline
Use this dialog box with the “Display Inline” option to insert an equation inline. You can use the equation toolbar to insert LaTeX code for the equation, or simply type it into the appropriate box. A preview area shows you how your equation will appear in your article.
Equations as Figures
You can also insert equations as a figure. For that, use the “Display as Figure” option, and include a Label and Caption:
Fig. 2: The Insert Equation Dialog – Figure
This figure shows how to insert an equation as a figure. The equation toolbar is being used to insert part of the equation.
Here are some simple equation examples. In all cases the LaTeX code used to create the equation is displayed in the Equation Caption. The examples presented here are based on these sample equations from Harvey Gould of Clark University.
Using some more advanced LaTeX commands, it is possible to insert more complex equations using Annotum:
