Explanation:

Sarah's teacher wrote this expression on the whiteboard. 24 ÷ 6 − 2 × 5 + 6 Where could she place brackets in the expression for it to be equal to 36? A. 24 ÷ [6 − 2] × 5 + 6 B. 24 ÷ 6 − [2 × 5 + 6] C. [24 ÷ 6] − 2 × 5 + 6 D. 24 ÷ 6 − 2 × [5 + 6]

Rule of operations

BODMAS

B = Bracket

O = 0f

D = Division

M = Multiplication

A = Addition

S = Subtraction.

Check all options

A. 24 ÷ [6 − 2] × 5 + 6

= 24 ÷ (4) × 5 + 6

= 6 × 5 + 6

= 30 + 6

= 36

B. 24 ÷ 6 − [2 × 5 + 6]

= 4 - (10 + 6)

= 4 - 10 + 6

= 0

C. [24 ÷ 6] − 2 × 5 + 6

= 4 - 10 + 6

= 0

D. 24 ÷ 6 − 2 × [5 + 6]

= 4 - 2(11)

= 4 - 22

= -18

Option A is the correct answer
