Yes, thank you very much sir.

oh... okay basically what it means is that all elements of A\B are contained inside A.

No definitions bro, just have to use x to prove it... That's why I'm confused.

Thank you very much for the correction. Well... there are no definitions, it just says let A, B and C be any set, prove that A\B⊂A.

Can some please explain to me how to solve these two questions? Let A, B and C be any sets, prove that: (a) A-B ⊂ A (b) (A∩B) complement = A complement ∪ B and (A∪B) complement = A complement∩ B complement.
