Rahul wants to count more blocks in his toy shop. Let us see how he counts more

than one hundred blocks.

Be Aware
There is a 0 in the tens place.
It means there are no tens.

H T O
100 5 105 1 0 5

One hundred five One hundred five
This is a collection of 105 blocks. The number name of 105 is one hundred five.

This way we can build numbers from 101 to 109 by keeping 1 in the hundreds place,

0 in the tens place and changing numbers from 1 to 9 in the ones place.
