### Example Question #4 : How To Subtract Odd Numbers

**Possible Answers:**

**Correct answer:**

Always start by gathering your facts. You know that if is odd, then *neither* of those numbers are even. (If either were, then the product would be even.) Now, the rules for subtracting are just like adding. If the difference of two numbers is even, then they must either both be odd or both be even. Thus if is even and we know that is odd, then we know that must be odd. Thus if is odd, it is also true that is even, for both and are even.
