Answer 3

Let's calculate each expression step by step:

1. 18 - (20 - 32) = 18 - (-12) = 18 + 12 = 30

2. -4 - (-5 + 21) = -4 - 16 = -20

3. 3.2 - (0.6 - 2.3) = 3.2 - (-1.7) = 3.2 + 1.7 = 4.9

4. (3.7 + 40) - 50 = 43.7 - 50 = -6.3

5. -9.5 - (-12.3 - 27.2) = -9.5 - (-14.9) = -9.5 + 14.9 = 5.4

6. -5.8 + (6.2 - 8.1) = -5.8 + (-1.9) = -7.7

So, the results of the given expressions are as follows:

1. 18 - (20 - 32) = 30
2. -4 - (-5 + 21) = -20
3. 3.2 - (0.6 - 2.3) = 4.9
4. (3.7 + 40) - 50 = -6.3
5. -9.5 - (-12.3 - 27.2) = 5.4
6. -5.8 + (6.2 - 8.1) = -7.7
