Brackets have the highest priority in BIDMAS, and are used to change the order in which calculations are carried out. Perform calculations *within* brackets first.

1. Add brackets to this expression to make it correct: 5 + 3 x 3 = 24.

Answer: (5 + 3) x 3 = 24

Add the 5 and 3 before the multiply. Without the brackets, the answer is 14.

2. Re-write this expression, putting brackets in the correct place: 12 - 6 x 2 + 2 = 24.

Answer: (12 - 6) x (2 + 2) = 24.

Work out the brackets first: (12 - 6) = 6 and (2 x 2) = 4 6 x 4 = 24

Calculate the answer of the calculations inside backets first.
