## Introduction to Formulas

Use formulas to make calculations as an end user is filling out a form.

Set up formulas by following these steps:

- Create a set of questions that will be used in the formula. These questions need to be of type Number, Currency, or Percent in order to be used a formula.
- Click
**Add Row**if additional questions are needed for the formula. - Use the row names (i.e. ROW1 * ROW2 * 100) in the formula line at the bottom to establish how the formula will be calculated.
- The indicator to the right will show green after validating the formula.

## Considerations for Formulas

- Formulas work both online and offline.
- A formula can exist as a simple question in a form template or as a field link. In the event of the latter, the final calculation would be saved to the appropriate field in Salesforce.
- Consider using rollup operators to create calculations across Linked Sections.
