Answer:
(a) 29. (b) 7. (c) 0. (d) 7.
Step-by-step explanation:
(a) 7 - {6 - 12 = (5 + 9 x 2 - 19)}}
- 7 - {6 - 12 = (5 + 18 - 19)}
- 7 - {6 - 12 = (23 - 19)}
- 7 - {6 - 12 = (4)}
- 7 - {-22}
- 7 + 22
- 29
(b) 14 - [{3 + (8 + (5 - 3 of 2 + 3)}]
- 14 - [{3 + (8 + (5 - 6 + 3)}]
- 14 - [{3 + (8 + (5 - 9)}]
- 14 - [{3 + (8 + (- 4)}]
- 14 - [{3 + (8 - 4 )}]
- 14 - [{3 + (4 )}]
- 14 - [ 7]
- 7
(c) 7 - [6 - {5 + (1 - 3 + 4)}]
- 7 - [6 - {5 + (1 - 7)}]
- 7 - [6 - {5 + ( - 6)}]
- 7 - [6 - {5 - 6 }]
- 7 - [6 - {- 1 }]
- 7 - [6 + 1 ]
- 7 - 7
- 0
(d) 5 - [3 - {2 - (2 x (-3) + 1) + (3-5)}]
- 5 - [3 - {2 - ((-6) + 1) + (-2)}]
- 5 - [3 - {2 - (-5) + (-2)}]
- 5 - [3 - {2 + 5 - 2 }]
- 5 - [3 - { 5 }]
- 5 - [-2]
- 5 + 2
- 7
Answer:
(a) 7 - {6 - 12 ÷ (5 + 9 x 2 - 19)}
= 7 - {6 - 12 ÷ (5 + 18 - 19)}
= 7 - {6 - 12 ÷ (23 - 19)}
= 7 - {6 - 12 ÷ 4}
= 7 - {6 - 3}
= 7 - 3
= 4
(b) 14 - [{3 + (8 + (5 - 3 of 2 + 3)}]
= 14 - [{3 + (8 + (5 - 3 × 2 + 3)}]
= 14 - [{3 + (8 + (5 - 6 + 3)}]
= 14 - [{3 + (8 + (5 - 3)}]
= 14 - [{3 + (8 + 2)}]
= 14 - [{3 + 10}]
= 14 - 13
= 1
(c) 7 - [6 - {5 + (1 - 3 + 4)}]
= 7 - [6 - {5 + (1 + 1)}]
= 7 - [6 - {5 + 2}]
= 7 - [6 - 7]
= 7 - 1
= 6
(d) 5 - [3 - {2 - (2 × (-3) + 1) + (3-5)}]
= 5 - [3 - {2 - (2 × (-3) + 1) + (-2)}]
= 5 - [3 - {2 - (-6 + 1) + (-2)}]
= 5 - [3 - {2 - (-5) + (-2)}]
= 5 - [3 - {2 - (-7)}]
= 5 - [3 - 5]
= 5 - 2
= 3
