You can add operators to a formula using the keypad, which contains buttons that help build formulas. It includes common operators (also referred to as functions).
To build a formula using keypad operators at the top of the window, follow these steps:
1. Open the Formula Editor by right-clicking a column name in the data table and selecting Formula.
2. Select a box in the formula editing area by clicking it. (It is selected when there is a blue outline around it.) The operator performs its action on the area that is highlighted.
3. Select the column or variable that you want to use in your formula.
4. Click the keypad button(s).
