Given two propositions, p and q, start out with p implies q. For example if a number is even it is a multiple of 2. So we are saying even implies multiple of 2.
Now the contrapositive is not p implies not q so if a number is not even it is not a multiple of 2. Or if not p then not q.
The contrapositive of the contrapositive would negate a negation so that would make it positive.
If not (not p) then not(not q) or in other words, you are back where you started, p implies q.

"contrapositive" refers to negating the terms of a statement and reversing the direction of inference. It is used in proofs. An example makes it easier to understand: "if A is an integer, then it is a rational number". The contrapositive would be "if A is not a rational number, then it cannot be an integer". The general form, then, given "if A, then B", is "if not B, then not A". Proving the contrapositive generally proves the original statement as well.
A is the negation and interchanging of the hypothesis and conclusion?
Contrapositive
