In this class, we will learn about the odd numbers, where do they start, their mathematical representation, examples for odd numbers, etc.

What are Odd Numbers

An odd number is any integer that is not exactly divisible by 2, meaning there is a remainder of 1, when the number is divided by 2.

Odd numbers usually end up with 1, 3, 5, 7, or 9.

Mathematical Notation of Odd Numbers

Mathematically, the set of odd numbers can be expressed as:

{ …, -5, -3, -1, 1, 3, 5, … }

Is 7 an odd number?

The given number 7 is an integer, and when divided by 2, leaves a remainder of 1.

Therefore, 7 is an odd number.

Is -5 an odd number?

The given number -5 is an integer and when divided by 2, leaves a remainder of 1.

Therefore, -5 is an odd number.

Is 4 an odd number?

The given number 4 is an integer, but when divided by 2, leaves a remainder of 0.

Therefore, 4 is not an odd number.
