Identifying even and odd numbers are topics in the mathematics scheme of work for primary school pupils. And in most cases, their teachers will want them to identify even and odd numbers from 1-100.
So, in this article, I will define even and odd numbers and give their examples for better understanding.
What is an Even Number?
These are numbers that can be easily divided by 2 without giving any remainder. They can as well be referred to as multiples of 2.
For example, from 1-100, the even numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 39, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100.
From the example I gave above, you will discover that if any of the numbers is divided by 2, the remainder will be zero (0) – meaning it has no remainder.
What is an Odd Number?
These are numbers that, when divided by 2, will give a remainder. For example, if you divide 3 by 2, it will give a remainder of 1. Also, dividing 5 by 2 will give a remainder of 1 (5 -:- 2 = 2 remainder 1). So, 3 and 5 are odd numbers.
Examples of odd numbers from 1-100 are 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. If you divide any of these numbers by 2, it will leave a remainder.
