Answer 1

1)-4,8
2)-5,7
3)-20,5
4)-8,5
5) -11,72
6) 9,1
7) -13,3
8) -6,9

Answer 2

Let's calculate the results for each of the expressions:

1. -0.18 - 3.9 = -4.08
2. 3.2 - 8.9 = -5.7
3. 12 - 32.5 = -20.5
4. 14 - 22.5 = -8.5
5. 12.1 - 23.82 = -11.72
6. -3.7 + 12.8 = 9.1
7. -17.2 + 3.9 = -13.3
8. -12.9 + 6 = -6.9

Please note that in expressions 1, 2, 3, 4, 5, 6, and 7, I used the "-" sign as subtraction. In expression 8, I used the "+" sign as addition. If you have any further questions or need more calculations, feel free to ask!
