Answer:
Marius is right.
Step-by-step explanation:
So although what Khalil said could be correct, they didn't say it right. It would be any two numbers the same distance from 0 <u>going the opposite ways</u>, which means that if you had 3 on one side, you would have -3 on the other side. BUt since Khalil said it wrong, he's basically saying that you can do 3+3 because they're both the same distance away from 0. or you could do (-3)+(-3)=-6 which would still work because they're the same distance away from 0. So unless you just skipped on that part while typing the question, Marius is correct.
