In the set of natural Numbers, every number is either odd or even, and there is not one even number that is more or less even than any other even number.

In either case, I take that value and multiply back by two, if it was even I get back the original number, if it was odd, I'm not going to get back the original number, so I can just check to see if they're the same.

If x was even, x divided by two is going to be actually the half of x, right?
