Why when you add 3 odd numbers together you get an odd number as the sum?

Because three odd numbers can be expressed as 2a + 1, 2b + 1 and 2c + 1. Adding these gives 2(a + b + c) + 3: 2(a + b + c) is obviously even, being a multiple of 2, and 3 is equally obviously 1 more than another even number, so your total comprises two even numbers plus 1, ie an odd number.
