Question

2. Simplify the following:
(i) 18 - [4 + {16 - (18-5)}]
(ii) 9 + {(45+5)= 3 - 2x 6}
(iii) 41 - [6 + {16 - (9-6)}]
(iv) 83 - [25 - {8 + (16 - 12)}]
(v) 80+ [56 + {7x 8 + (13 – 2x 5)}]
(vi) 10 - [15 - {8 -(6-8 - 2)}]​

Answer 1

1) 18 - (4 + (16 - ( 18 - 5)

18 - ( 4 + (16 - 13)

18 - ( 4.+ 3)

18 - 7 = 11

2) 9 + ( 45 + 5)= 3 - 2 *6)

9 + 50 = 3 - 12

9 + 50 = - 9

9 + 50 + 9 = 0

9 + 59 = 68

3) 41 - ( 6 + 16 - ( 9- 6))

41 - ( 6 + 16 - 3)

41 - 19 = 22

4) 83 - (25- (8 + (16 - 12)

83 - ( 25 - ( 8 + 4)

83 - (25 - 12)

83 - 13 = 70

5)80 + (56+ (7 * 8 + (13- 2*5

80 + 56 + 7 * 8 + 3

80 + 56 + 56 + 3 = 195

6)10 - ( 15-(8 - ( 6 -8 -2)

10 -( 15 - (8 + 4)

10 - ( 15 - 12)

10 - 3 = 7

hope it's help ✌✌
