Why is an odd number times an odd number always odd?

Correct answer:

Let us analyze I, II, and III one at a time. Because n and m are both even, if we increase either by 1, the result will be an odd number. Thus, n + 1 and m + 1 are both odd. When two odd numbers are multiplied together, the result is always an odd number.

Why is an odd number times an even number always even?

The sum of two odd numbers is always even, as is the sum of two even numbers. The sum of an odd number and an even number is always odd. In multiplication the product of two odd numbers is always odd. While the product of even numbers, as well as the product of odd numbers multiplied by even numbers is always even.

Why are two odd numbers added always even?

An odd number can be looked at as an even number with one added to it – e.g. 5 is 4+1. Therefore, if you add two odd numbers together, what you’re really doing is adding an even number to another even number, then adding 1 + 1, which is 2, and therefore even.
