Step-by-step explanation:
To copy a formula all the way down in a spreadsheet, you can use the fill handle or the fill command. The fill handle is a small square in the bottom-right corner of the active cell. To use the fill handle, click and drag it down to the desired number of cells. Alternatively, you can select the cell with the formula, go to the Edit menu, click on Fill, and then select Down.
For example, let's say you have a formula in cell A1 that adds the values in cells B1 and C1, and you want to copy it all the way down to cell A10. You can click and drag the fill handle in cell A1 down to A10, and the formula will be copied with the correct references to cells B1 and C1 for each row.
The fill handle can also be used to autofill a pattern, such as a series of numbers or dates, by dragging it down or across a selection of cells.
