In previous class we learnt that last 2-digit
number is 99.

100 is the first three-digit number.

Let us see that

99 + 1 = 90 + 9 + 1

2-digit = 9 tens + 1 ten
numbers
= 10 tens

So 10 tens is equal to 100.

100 is written as hundred .

100 is the smallest three-digit number.

In a 3-digit number, the first place from right is one’s .
