An odd number is an integer that is not a multiple of two. Examples: -7, 1, 15, 43.
Odd numbers are the opposite of
even numbers.
A lotto number must be either odd or even. In a lotto drawing, the set of numbers usually include some odd and some even numbers, so it is good to include some of both when you are playing lotto tickets.
