i + ORDER OF OPERATION
When performing calculations using a formula, Excel follows certain rules of precedence:
• Excel calculates expressions within parentheses ‘(‘ , ’)’ first.
• Excel calculates multiplication and division before addition and subtraction.
• Excel calculates consecutive operators with the same level of precedence from left to right.
For example, the formula = 10 + 10 * 2 gives a result of 30, as Excel multiplies 10 by 2 and then
adds 10.
However, the formula =(10 + 10)*2 produces a result of 40. This is because Excel calculates the
expression (10 + 10) within the parentheses first. It then multiplies that result by 2.
If you are unsure of the order in which Excel calculates, use parentheses even if the parentheses
aren’t necessary. Parentheses also make your formulas easier to read.
