Hello there!
The additive inverse of any number just means to flip it's value.
For example;
The number "3" would have an additive inverse of "-3".
The number "-15" would have an additive inverse of "15".
Since we have "52", we can flip the value sign of it.
We now have -52 and 52.
Since the question asked us to sum our numbers, we need to add them.
-52 + 52 = 0
The sum of 52 and its additive inverse is 0.
I hope this helps!
