In spreadsheets such as Lotus 1-2-3, an absolute cell address identifies the location a cell or group of cells.
An example of an absolute cell address would be $C$4, $G$15, or $A$345.
Note: An easy way to add the dollar signs to a cell address is to click on a cell address and then press the F4 key on the keyboard.
An absolute cell address is used when you want a cell address to stay fixed on a specific cell.
By contrast, most cell addresses in a spreadsheet are relative cell addresses, which change when copied and pasted to other cells.
