Answer 3

It seems like you've provided a series of mathematical calculations. Let's go through each one step by step:

1. 1.5 + 2.5 = 4.0
2. 2.6 - 0.25 = 2.35
3. 3.69 - 0 = 3.69
4. 4.25 - 4.6 = -0.35
5. 5.27 + 0.23 = 5.5
6. 6.18 + 2.5 = 8.68
7. 7.52 - 1.2 = 6.32
8. 8.0.55 + 0.45 = 9.0
9. 9.4 - 0.8 = 8.6
10. 10.1 - 0.45 = 9.65
11. 11.64 + 0.36 = 12.0
12. 12.57 + 3 = 15.57
