Whats the opposite of subtraction?

OpenStudy (anonymous):

addition :D

pooja195 (pooja195):

Good ^_^ So we would ADD 7 to cancel it out and so that we have b all alone :-) SOOO -9+7=?

-2!! YAAY THANK YOU SO MUUCH!!! I GOT -16 Somehow...

pooja195 (pooja195):

You got -16 because you subtract 7 from both sides and you weren't supposed to do that :P But you're welcome ^_^ Thanks for interacting and participating :)
