These are the words that we use to represent numbers, which makes it easier to read.

Writing numbers in words not only helps us write legal documents and fill forms,
but it also helps a student's spelling skill as well.

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

Understanding how numbers are named using both numbering systems
will assist in communication as well as arithmetic calculations.

Now let’s discuss the two numbering systems.

Indian Numbering System

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 73, the digit 3 is in the ones place, and 7 is in the tens place.

Starting from the right, the order goes from:
ones → tens → hundreds → thousands → ten thousands → lakhs → ten lakhs → crores

Each digit will have its value based on its position in the number.

Let’s take an example of the number 62,743
The number is written as Sixty-Two Thousand Seven Hundred Forty-Three

The number gets placed as:
6 in the ten thousands place
2 in the thousands place
7 in the hundreds place
4 in the tens place
3 in the ones place

International Numbering System

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 74,365,269.
The number is written as:
Seventy-Four Million Three Hundred Sixty-Five Thousand Two Hundred Sixty-Nine

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