Answer 2

10+(-6)=4.
99+(-1)=98.
23+(-7)=16.
-2.9+0.9=-2
84+(-4)=80.
5.6+(-8.7)=-3.1

Answer 3

Let's calculate each of these expressions:

1. 10 + (-6) = 4
2. 99 + (-1) = 98
3. 23 + (-7) = 16
4. -2.9 + 0.9 = -2
5. 84 + (-4) = 80
6. 5.6 + (-8.7) = -3.1

So, the results are:

1. 4
2. 98
3. 16
4. -2
5. 80
6. -3.1
