Formulas start with =
A spreadsheet formula starts with = and works out a result from cell values. This one adds A1 and B1, and the answer shows in the cell.
Understanding Formulas start with = in Years 5–6 Data & Information
What it does: The = at the start makes this a formula. It subtracts B4 from B3 and shows the result in the cell. Typing 12 puts the number 12 in the cell. A formula like =A1+B1 would work it out instead. Every formula starts with =. This tells the spreadsheet to calculate instead of just showing what you typed. 15 is a typed value that you entered yourself. =A1+B1 is a formula that calculates its answer from other cells. Only =A1+B1 is a formula, so it calculates 2 + 7 = 9. Without the =, C1 would just show the text A1+B1.
Common mistakes: The cell shows the result of the formula, not the formula itself. C1 should show 12, which is 5 + 7. A formula must start with an equals sign. Without it the spreadsheet treats A1+B1 as plain text. It should be =A1+B1.
