A. I’ll show you an easy way, but you really should not be resistant to macros; they are very powerful tools.
To save and store a formula, begin by typing it into a cell (for example, =A1+B1 ). Now press F2, which puts Excel in the edit mode. Hold down the Shift key, highlight the formula (see screenshot below) and copy (Ctrl+C) it to the Clipboard.
Now get out of the edit mode by pressing Esc, go to the toolbar and click on Insert and Name , evoking the Define Name screen. In the space next to Names in workbook , type in a name for your formula— add_it . Note that the name must be one word, so if you use more, connect them with an underline dash (_).
Place your cursor in the box below Refers to . It will contain a reference to the location of the formula; ignore it and paste (Ctrl+V) your formula (which is still in the Clipboard) into the box (see screenshot below). Click on OK .
Whenever you want to use the formula, place your cursor in the cell where you want the formula to appear and type an equal sign plus the name you gave to the formula ( =add_it ). It will be copied into the cell and ready to work.
