Hi, I'm new to these forums so please redirect me if I've posted this in the wrong place.

I'm trying to graduate and this is my last class, but as I'm not a math major, I'm really struggling with this particular problem. I've been able to manage most other simple proofs pretty well, but this one has me stumped:

(A∪B)-(A∩B)=(A-B)∪(B-A)

The instructor hinted that this problem could/should be done with Proof by Cases. Any chance someone could walk me through this?? Like I said, I've managed to handle other similar problems but the elements of this one have me thrown.... any help would be appreciated. I tend to learn well by example, but there's nothing in my notes/textbook that show a similarly structured problem...

Thanks!
