    It's asking how much the temperature fell so if it started at 10 and dropped to negative 2 this is one of the few cases you add them together and get 12 in other cases that aren't asking for a total like 10 + (-2) it would be 8 but in this case it's 10+2 since its asking for a temperature drop instead of it being an algebra problem.
