For example — Take a number 37542
Put this number in table written below :

Thousands Ones

Ten thousands Thousands Hundreds Tens Ones
(TTh) (Th) (H) (T) (O)

3 7 5 4 2

As we observe 3 and 7 are in thousand column and 5, 4 and 2 are in ones

column.
It is read as thirty-seven thousand five hundred and forty-two.

Note
In order to write by numbers, we separate the periods by putting comma (,). Here 37542 is written as 37,542.

Forming 6-digit Numbers
We know, 99999 is the greatest 5-digit number. If we add 1 to it, we get

99999 + 1 = 100000
It is read as one lakh.

Take a number 297385.

Lakh Thousands Ones

three hundred eighty-five.

To put commas in this number, we write it as 2,97,385
