    Then there's no question. If AnB hasn't been defined, you can't really know what you're trying to prove.

    I'd define AnB as {x : x is in A and x is in B}. Can you prove it from there? (To show that two sets C and D are equal, you should show separately that every x in C is also in D, and every y in D is also in C.)
