Answer 2

Let's solve each of these math problems step by step:

1. 42 + 24 - 24 = 42 + 0 = 42
2. 43 + (43 - 15) = 43 + 28 = 71
3. 0 • 21 + 20 = 0 + 20 = 20
4. 40 + 8 • 5 = 40 + 40 = 80
5. 7 • 9 - 54 = 63 - 54 = 9
6. 0 • 67 - 9 = 0 - 9 = -9
7. 64 ÷ 8 - 72 ÷ 9 = 8 - 8 = 0
8. 35 - 81 ÷ 9 = 35 - 9 = 26
9. 35 - 35 • 0 = 35 - 0 = 35
