How do I copy a formula to multiple cells in Google Sheets?

To copy a formula to multiple cells in Google Sheets, you can follow these steps:

1. Select the cell containing the formula you want to copy.
2. Click on the small blue square in the bottom-right corner of the selected cell and drag it over the range of cells where you want to copy the formula.
3. Release the mouse button.

Alternatively, you can also use the keyboard shortcut Ctrl + Shift + Enter to copy the formula to multiple cells.

It's important to note that when you copy a formula to multiple cells, the cell references in the formula will change automatically based on the relative position of each cell to the original cell. For example, if your original formula references cell A1 and you copy it to a cell three columns to the right, the formula will automatically update to reference cell D1.
