In Excel, you can type in formulas into a cell so that you don’t have to type and type the same information into each cell. There may be a pattern to your data. You can create a formula into one cell and it will apply it to the other cells that you have designated as the ones that you want involved in the cells.

When you type in an equal sign at the beginning of a formula in Excel, that means that a calculation is about to be typed in. Then you would need to type the cell where you want the answer to be placed. Usually, a set of parentheses are typed into the formula to include the rest of the formula.
