<i>Murray said, “But the odd integers can be derived. If you divide every even integer in the entire infinite series by two, you will get another infinite series which will contain within it the infinite series of odd integers.”</i><p>For S={2,4,6,8...}<p>S/2={1,2,3,4,..}<p>I used to think the set of even integers is a subset of the natural numbers.Doesnt this suggest that the reverse (the set of natural numbers being a subset of even integers) is actually true?
