Answer 3

Let's calculate each expression step by step:

1. -15 + (-18) = -15 - 18 (Adding a negative number is the same as subtracting its positive counterpart.) = -33

2. -0.5 + 6 = 5.5 (Adding a positive number.)

3. -2.4 + (-3.2) = -2.4 - 3.2 (Adding a negative number is the same as subtracting its positive counterpart.) = -5.6

4. 6.1 + (-8.3) = 6.1 - 8.3 (Adding a negative number is the same as subtracting its positive counterpart.) = -2.2

So the results are as follows:

1. -15 + (-18) = -33
2. -0.5 + 6 = 5.5
3. -2.4 + (-3.2) = -5.6
4. 6.1 + (-8.3) = -2.2
