Number Names 20 to 50

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

Writing numbers in words not only helps when filling out forms and writing legal documents, but it also supports a student’s spelling development.

There are two ways of naming numbers:

1. Indian Numbering System

2. International Numbering System

Understanding both systems helps with communication and arithmetic calculations.

Now, let’s explore these two numbering systems.

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

For example, in the number 46:

• 6 is in the ones place

• 4 is in the tens place

The order from right to left is:
Ones → Tens → Hundreds → Thousands → Ten Thousands → Lakhs → Ten Lakhs → Crores

Each digit's value depends on its position in the number.

Let’s look at 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. These values include:

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

Let’s take the example 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 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
