Order of operations (BIDMAS)
Evaluate expressions using the correct order of operations.
- Brackets first, then indices (powers and roots).
- Division and multiplication have equal priority. Work from left to right.
- Addition and subtraction have equal priority. Work from left to right.
- In each example, calculate the underlined part next.
Example 1
Evaluate the expression.
Example 2

Remember
BIDMAS does not mean that division always comes before multiplication. They share a priority.
