Решение:

1. \( (37 - 7) - 9 = 30 - 9 = 21 \)
2. \( (84 - 4) - 2 = 80 - 2 = 78 \)
3. \( (55 - 5) - 7 = 50 - 7 = 43 \)
4. \( (28 - 8) - 4 = 20 - 4 = 16 \)
5. \( (62 - 2) - 1 = 60 - 1 = 59 \)
6. \( (96 - 6) - 3 = 90 - 3 = 87 \)
7. \( (63 - 3) - 8 = 60 - 8 = 52 \)
8. \( (49 - 9) - 5 = 40 - 5 = 35 \)
9. \( (71 - 1) - 6 = 70 - 6 = 64 \)
10. \( (54 - 4) - 2 = 50 - 2 = 48 \)
