Formulas contain information to perform a numerical calculation such as adding, subtracting, or multiplying. All formulas must start with an equal sign (=), followed by:
- Values or cell references joined by an operator. Example: =5+3 or =A1+A2.
- A function name followed by parentheses containing function arguments. Functions are the most common way to enter formulas in Sheets. Example: =SUM(A1:A2).
- Select the cell where you want to enter a formula.
- Press =.
- Enter the formula.
- Add cells by clicking them or typing their cell reference.
- Operators include:
- Press Enter when you're finished.
If you entered the formula correctly, the results of the formula will appear in the cell.
|=||All formulas must start with an equal sign.|
|SUM||=SUM(A1:A3)||Totals numbers in a range.|
|AVERAGE||=AVERAGE(A2,B1,C3)||Averages numbers in a range.|
Every time a cell that a formula references is updated, the formula result updates as well. Let's see that in action.
- Formulas will automatically recalculate when changes are made to referenced cells.
- Select the cell where you want to edit a formula.
- Click in the formula bar.
- Edit the formula in the formula bar.
- Press Enter.
The formula is edited based on the changes you made to it.
