A^closure = X\(X\A)^interior
I am REALLY bad at proofs. I never know where to start. I only have the definitions of closure and interior. I feel like they threw us in the deep end
I've written like 3pages, but mostly just pictures.
interior: a is an element of A^int iff there exists r>0 with B(a,r) subset of A
and
closure: a is an element of A^closure iff for all r>0, B(a,r)(and)A are not empty
