How do you calculate odd numbers?

How do you determine if a number is odd or even? If a number is evenly divisible by 2 then it’s an even number, otherwise, it’s an odd number. We can also say when we divide a number by 2 and there is some remainder left, which is not divisible again by 2, then it’s an odd number.
