Relative and absolute cell references
The dollar signs lock a cell reference, so $B$1 stays fixed when a formula is copied. A plain B1 is relative and shifts to match its new position. B$1 locks only the row.
Understanding Relative and absolute cell references in VCE Spreadsheets, SQL & Visualisation
What it does: With no dollar signs, both references are relative. Copied down one row, the formula becomes =A3+B3. A dollar sign before the column letter and another before the row number lock both parts, so the reference stays on B1. $B$1 keeps pointing at the GST rate. With B1, the reference would slide down to B2, B3 and so on, and pick up the wrong cells. The $ sits in front of the 1, so the row is locked. The column B can still change when the formula is copied across. $B$1 is absolute so it never changes. Only the relative A2 shifts down to A3.
Common mistakes: E1 is relative, so when the formula is copied down it shifts to E2, E3 and so on. The rate must be locked as $E$1 so every row uses the same cell. $B$2 is locked, so every copy would multiply the first price. The price B2 should be relative so it moves to B3, B4 and so on when copied down.
