Inner Bracket Bracket Division Addition Answer |
Problem 2 :
4 × [(4 × 3) ÷ 2] × 7
Solution :
= 4 × [(4 × 3) ÷ 2] × 7 = 4 × [12 ÷ 2] × 7 = 4 × 6 × 7 = 168 |
Inner Bracket Division Multiplication Answer |
Problem 3 :
[(2 × 3) + (11 – 5)] ÷ 3
Solution :
= [(2 × 3) + (11 – 5)] ÷ 3 = [6 + 6] ÷ 3 = 12 ÷ 3 = 4 |
Inner Brackets Bracket Division Answer |
Problem 4 :
19 – [{3 × 7} – {9 ÷ 3}] + 14
Solution :
= 19 – [{3 × 7} – {9 ÷ 3}] + 14 = 19 – [21 – {9 ÷ 3}]+ 14 = 19 - [21 - 3}] + 14 = 19 – 18 + 14 = 1 + 14 = 15 |

Problem 11 :
(5 - 2)^{2} – 2^{2}
Solution :
= (5 - 2)^{2} – 2^{2} = 3^{2} – 4 = 9 – 4 = 5 |
Subtraction Square Subtraction Answer |
Problem 12 :
(15 – 3^{2}) ÷ 3
Solution :
= (15 – 3^{2}) ÷ 3 = (15 – 9) ÷ 3 = 6 ÷ 3 = 2 |
Exponent Bracket Division Answer |
Problem 13 :
5 × (2^{2} + 2) + 6
Solution :
= 5 × (2^{2} + 2) + 6 = 5 × (4 + 2) + 6 = 5 × 6 + 6 = 30 + 6 = 36 |
Brackets, exponent Bracket Multiplication Addition Answer |
Problem 14 :
35 – 3 × 2^{3} + 7
Solution :
= 35 – 3 × 2^{3} + 7 = 35 – 3 × 8 + 7 = 35 – 24 + 7 = 42 – 24 = 18 |
Exponent Multiplication Addition Subtraction Answer |
Problem 15 :
(3 × 7 – 5)/2
Solution :
= (3 × 7 – 5)/2 =(21 – 5)/2 = 16/2 = 8 |
Multiplication Subtraction Division Answer |
Problem 16 :
[3 × (7 – 5)]/2
Solution :
= [3 × (7 – 5)]/2 = [3 × 2]/2 = 6/2 = 3 |
Subtraction Multiplication Division Answer |
Problem 17 :
(56 ÷ 8 – 7)/(56 ÷ (8 – 7)
Solution :
= (56 ÷ 8 – 7)/(56 ÷ (8 – 7))
= (7 – 7)/(56 – 1)
= 0/ 1
= 0
Problem 18 :
[25 – (16 – 11)]/[(12 ÷ 4 + 2)]
Solution :
= [25 – (16 – 11)]/[(12 ÷ 4 + 2)]
= [(25 – 5)]/[(3 + 2)]
= 20/5
= 4
