Answer:
C : None of the above
Step-by-step explanation:
A : -2+(-2) = 0 False
-2+(-2) = -4
A negative plus a negative is actually a negative. When adding signed numbers, it is useful to think of positive numbers as gains and negative numbers as losses.
B : 2-(-2) = 0 False
2-(-2) = 4
Because there is subtraction sign so if subtraction sign added to negative sign it makes positive from 2-(-2) it will be 2+2
