I am trying to understand the concept of an isomorphism. I encountered the following problem:

Find the isomorphism between ({odd, even}, +) -> ({positive, negative}, x). To me it is clearly an isomorphism because all I am doing is replace odd with +ve, even with -ve and + with x. But is there an actual map that does this here?
