### Copying Formulas

Often times a formula in one cell is needed in other cells. This often occurs within the same row or column. Excel makes it easy to copy them by changing the cells in the formula to the correct cell when the formula is copied in the following manner:- Hover the cursor over the bottom right corner of the cell with the original formula until the cursor turns into the black/thinner
**+**. **Left-click and drag**until the formula has been copied into all the desired cells. Release the mouse button and the formula will have been copied to the cells.
