Решение:

1. \( 7.3 + 3.5 = 10.8 \)
2. \( 2.5 + 3.3 = 5.8 \)
3. \( 0.00 - 3 = -3.00 \)
4. \( 0.5 + 1.8 = 2.3 \)
5. \( 0.67 + 2.9 = 3.57 \)
6. \( 0.00 - 5 = -5.00 \)
7. \( 2.4 + 4 = 6.4 \)
8. \( 0.2 + 56 = 56.2 \)
9. \( 90.0 - 9 = 81.0 \)
10. \( 0.57 + 6.0 = 6.57 \)
11. \( 6.9 + 12 = 18.9 \)
12. \( 7.0 - 0.87 = 6.13 \)
13. \( 0.77 + 2.0 = 2.77 \)
14. \( 2.2 + 0.0 = 2.2 \)
15. \( 0.00 - 2.6 = -2.60 \)
16. \( 0.72 + 1.9 = 2.62 \)
17. \( 0.8 + 2.4 = 3.2 \)
18. \( 85.0 - 6.6 = 78.4 \)
