Number Names 21 to 40

These are the words that we use to represent numbers, which makes them easier to read. Take the number 25, it is written as ‘Twenty-Five’.

Writing numbers in words not only helps us with legal documents and filling forms, but it will also enhance a student's spelling skills.

There are two different ways of naming numbers: the Indian Numbering System and the International Numbering System.

You need to understand how numbers are named in both systems. This will aid in communication as well as arithmetic calculations.

Now, let’s discuss the two numbering systems.

In the Indian Numbering System, digits are assigned place values starting from the right. These place values include ones, tens, hundreds, and thousands, and continue to grow as the number increases.

For example, in the number 34, the digit 4 is in the ones place, and 3 is in the tens place.

Starting from the right, the order goes from ones to tens, hundreds, thousands, ten thousands, lakhs, ten lakhs, and crores. Each digit has its value based on its position in the number.

Let’s take an example of the number 9,56,28,743:

The number gets written as Nine Crore Fifty-Six Lakhs Twenty-Eight Thousand Seven Hundred Forty-Three.

The number gets placed as:
9 in the crores place
5 in the ten lakhs place
6 in the lakhs place
2 in the ten thousands place
8 in the thousands place
7 in the hundreds place
4 in the tens place
3 in the ones place

Just like the Indian Numbering System, the International Numbering System also uses names, and they differ for bigger numbers.

The place value starts from the right. The place values are ones, tens, hundreds, thousands, hundred thousands, millions, ten millions, hundred millions, and so on.

Let’s take the example of 743,856,269:

The number is written as Seven Hundred Forty-Three Million Eight Hundred Fifty-Six Thousand Two Hundred Sixty-Nine.

The number gets placed as:
7 in the Hundred Million place
4 in the Ten Million place
3 in the Million place
8 in the Hundred Thousands place
5 in the Ten Thousands place
6 in the Thousands place
2 in the Hundreds place
6 in the Tens place
9 in the Ones place
