Even numbers are divisible by 2, while odd numbers aren’t.
This means that if you divide an even number by 2, you’ll always get a whole number result (e.g. 10/2 = 5). On the other hand, if you divide an odd number by 2, you’ll get a fractional result (e.g. 9/2 = 4.5).
Keeping this rule in mind can be really helpful when it comes to doing things like addition, subtraction, multiplication and division.
In fact, this divisibility rule can be applied to any even or odd number, not just those between 1 and 100!

Knowing whether a number is odd or even can be helpful in lots of situations. For example, when adding or subtracting numbers, you can pair up odd numbers with odd numbers and even numbers with even numbers to make calculations easier.
For multiplication and division questions, you can also use the fact that odd numbers always give odd results when multiplied together, and even numbers always give even results (except 0).
All odd numbers end in 1, 3, 5, 7 and 9. As a result, every odd number written in word form ends in the letter ‘e’. Isn’t that cool?!
Most students are introduced to the concept of odd and even numbers in first or second grade. According to common core math standards, odd and even numbers are introduced in second grade.
Odd numbers from 1 to 100 include: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99.

Integers can only be even or odd. No number is both even and odd.
Zero is considered an even number in math.
All prime numbers except for 2 are odd. This is because a prime number can only be divided by 1 and itself. Therefore, the result will always be an odd number.
Some examples of prime numbers are:
3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47.
