Letʼs learn my dear friends
The story of numbers
There are hundreds, tens, and ones
Hundreds number has three digits

Arrange numbers in two ways
Ascending order makes numbers larger
Descending order makes numbers smaller
Easy learning, we are all happy!

Now it is the time to round off
If it is the tens which is asked
Look at the value of the ones
If it is less than 5
So zero it will be

Now we are rounding off to hundreds
