The air temperature is -7 degrees.
1) the air temperature has changed by +3; by +2.
The air has become warmer, therefore:
-7 + 3 = -4 degrees;
-7 + 2 = -5 degrees.
2) the air temperature changed by -2; by -4.
The air has become even colder, therefore:
-7 – (-2) = -7 + 2 = -9 degrees;
-7 – (-4) = -7 + 4 = -11 degrees.
