Answer:
1. 32
2. 30
3. 0
Step-by-step explanation:
1. 37 - [45 - 4 x (39 - 29)
= 37 - (45 - 4 x 10)
= 37 - (45 - 40)
= 37 - 5
= 32
2. 12 + 3 x {3 x [4 + (9 - 8) - 2] - 3}
= 12 + 3 x [3 x (4 + 1 - 2) - 3]
= 12 + 3 x (3 x 3 - 3)
= 12 + 3 x (6)
= 12 + 18
= 30
3. 14 - 2 x {2 + 5 x [7 + 3 x (15 - 12) - 15]}
= 14 - 2 x [2 + 5 x (7 + 3 x 3 - 15)]
= 14 - 2 x [2 + 5 x (7 + 9 - 15])
= 14 - 2 x (2 + 5 x 1)
= 14 - 2 x 7
= 14 - 14
= 0
Hope this helps!
