Answer 3

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

1. -2.1 + (-0.4) + (-7.9) + (-4.6) = (-2.1) + (-0.4) + (-7.9) + (-4.6) = -2.1 - 0.4 - 7.9 - 4.6 = -2.1 - 0.4 - 7.9 - 4.6 = -15.0

2. -8.3 + (-4.5) + (-1.7) + (-5.5) = (-8.3) + (-4.5) + (-1.7) + (-5.5) = -8.3 - 4.5 - 1.7 - 5.5 = -8.3 - 4.5 - 1.7 - 5.5 = -20.0

3. -37 + (-22) + (-13) = (-37) + (-22) + (-13) = -37 - 22 - 13 = -37 - 22 - 13 = -72

4. 42 + (-45) + (-12) = 42 + (-45) + (-12) = 42 - 45 - 12 = 42 - 45 - 12 = -15

So, the results are:

1. -15.0
2. -20.0
3. -72
4. -15
