Answer: A and B

Explanation: A sum is an answer to an addition problem and a difference is the answer to a subtraction problem. N is the sum to the addition problem and - n is the answer to a subtraction problem.

Answer is A

You can plug numbers in to check:

a) n=5

5 + (-5) = 0

b) n=5

5 - (-5) = 5+5=10

c) n=5

5 (-5) = -25

d) n=5

5/-5=-1
