thanks !!

how do i check if a number is not divisible by 2?

not divisible by 2 == odd.

Or you could read what % does.

Or ... and so on.

The modulus operator (%) returns the remainder of a division. So say you divide 3 by 2. The remainder is 1. If the remainder is 0, the number must be even; otherwise, if it is odd, the remainder is not 0.
