Number Names 21 to 30

These are the words that we use to represent numbers, which makes it easier to read. Take the number 25; it is written as 'Twenty-Five'. Writing numbers in words not only helps us write legal documents and fill forms, but it also enhances a student's spelling skills. There are two different ways of naming numbers: the Indian Numbering System and the International Numbering System. Understanding how numbers are named using both systems will assist you 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 include:

Ones → Tens → Hundreds → Thousands → Ten Thousands → Lakhs → Ten Lakhs → Crores, and so on.

For example, take the number 28:

• 8 is in the ones place

• 2 is in the tens place

Now let’s consider the number 9,56,28,743.
It is written as:
Nine Crore Fifty-Six Lakhs Twenty-Eight Thousand Seven Hundred Forty-Three

The digit placement is as follows:

• 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

In the International Numbering System, digits are assigned place values starting from the right. The order of place values is:

Ones → Tens → Hundreds → Thousands → Ten Thousands → Hundred Thousands → Millions → Ten Millions → Hundred Millions, and so on.

Let’s take the number 743,856,269.
It is written as:
Seven Hundred Forty-Three Million Eight Hundred Fifty-Six Thousand Two Hundred Sixty-Nine

The digit placement is as follows:

• 7 in the hundred million place

• 4 in the ten million place

• 3 in the million place

• 8 in the hundred thousand place

• 5 in the ten thousand place

• 6 in the thousand place

• 2 in the hundreds place
