## Learn how to add and format equations in your instructions.

With Cadmus, you can add equations to your instructions using the formatting toolbar. Your students will have access to the same options when creating their submissions.

This article covers:

### Inserting equations

Equations can be added in two formats — as a block equation (centred on a new line) or as an inline equation (embedded within a paragraph). Regardless of the style you choose, you can create and edit equations in the same way.

**TIP**! Break up long equations by inserting multiple equations on new lines.

**To insert an equation**

- Click the
**Equation**icon in the Formatting Toolbar. - Select
**Block**or**Inline**equation. - Type in your equation using the on-screen keyboard or computer keyboard.
- You can also input your equation using LaTeX, by toggling on
**Show LaTeX**and typing in the LaTeX field. - When you’re finished, click the blue
*Done*button in the bottom-right corner of the on-screen keyboard. - If you need to edit the equation, simply click on it to bring up the on-screen keyboard again.
