Numbers are very necessary in our life. Those are used to count the things. We know numbers

one, two, three, four excetra and their respective symbols 1,2,3,4… This is a group of numbers.

A group of numbers 1,2,3,4… is the set of counting numbers.

This set of numbers is called the **Set of** **natural numbers** and the numbers in this set are called **Natural Numbers**.

The symbol for set of **Natural Numbers** is ‘N’.

We can write it as;

N={1, 2, 3, 4, 5, 6, 7, 8, 9….. }

That is, set of **natural numbers** starts from 1.

We can say that-

1 The value of **natural number** is increased from left to right.

2 The smallest **natural number** is 1.

3 If we go further from left to right, we get more numbers. There are innumerable numbers. There is no end to these numbers. So we cannot tell the biggest **natural number**.
