# Inserting mathematical and chemical equations

Use the equation tool to add mathematical and chemical equations to a presentation page. This tool includes MathType and ChemType tabs so you can easily find and add common symbols for building equations.

After adding the equations, you can keep the page as a presentation page for instruction and modeling, or convert the page to an Individual Handout, Group Workspace, or Whole-class Whiteboard activity.
