Explanation:

BIDMAS gives the strict order of operations in mathematics: Brackets first, then Indices (powers and roots), then Division and Multiplication, and finally Addition and Subtraction.

Division and Multiplication have equal priority (work from left to right). Similarly, Addition and Subtraction have equal priority (work from left to right — do not automatically add before subtracting if subtraction comes first on the left).

Example 1: Work out 18 − 3 × 4 + 2²

Solution:

1. Indices: 2² = 4 → 18 − 3 × 4 + 4

2. Multiply: 3 × 4 = 12 → 18 − 12 + 4

3. Add/Subtract (left to right):

• 18 − 12 = 6, then 6 + 4 = 10

Answer: 10

Example 2: Work out 36 ÷ (11 − 2) + 5 × 3²

Solution:

1. Brackets: (11 − 2) = 9 → 36 ÷ 9 + 5 × 3²

2. Indices: 3² = 9 → 36 ÷ 9 + 5 × 9

3. Divide & Multiply: 36 ÷ 9 = 4 and 5 × 9 = 45

4. Add: 4 + 45 = 49

Answer: 49
