Definition of Even and Odd Numbers

Generally, the even and odd numbers are defined as follows:

Definition 1: “Even numbers are those numbers which are divisible by 2 and odd numbers which are not divisible by two”.

Definition 2: “Even numbers are those which when divided by 2 leaves no remainder or as 0 and Odd numbers are those numbers which when divided by 2 leaves a remainder of 1”.

How to Check a Number is an Even or Odd Number?

As we know now that “Even numbers those numbers which end with 0,2,4,6,8 and odd numbers are those numbers which end with 1,3,5,7,9.”

So, first, look at the number in the one’s place. This single number will tell whether the entire number is odd or even.

Let us take a number 1131. To check whether the given number is even or odd, first, divide the number by 2.

While dividing the number 1131 by 2, we get the remainder 1. So, the given number 1131 is an odd number.
