Quiz- 1

You need to do the operation, or sum, inside the brackets first, 3 + 2, then multiply the answer by 4.

3 + 2 = 5.
4 × 5 = 20

If you ignored the brackets and did the sum 4 × 3 + 2 you would get 14. You can see how the brackets make a difference to the answer.

You need to do the power sum first, before you can add 5.

3² = 3 × 3 = 9
9 + 5 = 14

You need to do division and multiplication first, but you have one of each.

Start from the left and work across to the right, which means that you start with 4 × 5 = 20. Then do the division, 20 ÷ 2 = 10.

Only then do you move to the addition: 10 + 7 = 17. The answer is 17.

You simply start on the left and work your way across.

4 + 6 = 10
10 - 7 = 3
3 + 3 = 6
The answer is 6.

3 + 6 x (5 + 4) ÷ 3 - 7
3 + 6 x 9 ÷ 3 - 7
3 + 54 ÷ 3 - 7
3 + 18 - 7
21 - 7
=14

9 - 5 ÷ (8 - 3) x 2 + 6
9 - 5 ÷ 5 x 2 + 6
9 - 1 x 2 + 6
9 - 2 + 6
7 + 6
=16

150 ÷ (6 + 3 x 8) - 5
150 ÷ (6 + 24) - 5
150 ÷ 30 - 5
5 - 5
=0
