Below the value in A1 has changed from 10 to 12: Now we can easily change the value in A1, and all three formulas recalculate. Notice the reference to D1 updates when the formula is copied, but the reference to A1 never changes. This means the reference is relative to the cell it lives in. The cell references above are called relative references. This means you don't need to enter the same basic formula again and again. In the screen below, the formula in E1 has been copied to the clipboard with Control + C:īelow: formula pasted to cell E2 with Control + V.
