### 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.

- Click the
**Equation**icon in the Formatting Toolbar. - Select

*Insert*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.
