Answer 2

Let's calculate the given expressions:

1. -4 + 7 = 3
2. 3 + 8 = 11
3. -2 + 9 = 7
4. -1 + 10 = 9
5. -4 + (-7) = -11
6. -3 + (-8) = -11
7. -2 + (-9) = -11
8. -1 + (-10) = -11

Here are the results for each expression:

1. -4 + 7 = 3
2. 3 + 8 = 11
3. -2 + 9 = 7
4. -1 + 10 = 9
5. -4 + (-7) = -11
6. -3 + (-8) = -11
7. -2 + (-9) = -11
8. -1 + (-10) = -11
