Number names are a way of expressing numbers in their written form using letters. Learning number names will aid in mastering the basics of counting, addressing parcels, filling out official documents, and more. In this topic, we will learn number names from 100 to 1000.

Number Names 100 to 1000

Number names are words used to represent numbers, making them easier to read and write.
For example, the number 250 is written as ‘Two Hundred Fifty’.

Writing numbers in words not only helps with legal documents and form-filling, but also improves a student's spelling and number sense.

There are two different ways of naming numbers:

  • The Indian Numbering System

  • The International Numbering System

Understanding both systems will help with better communication and more accurate arithmetic calculations.

Let’s now explore these two numbering systems.

Indian Numbering System

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

For example, in the number 786:

  • 6 is in the ones place

  • 8 is in the tens place

  • 7 is in the hundreds place

The full order of place values is:
Ones → Tens → Hundreds → Thousands → Ten Thousands → Lakhs → Ten Lakhs → Crores

Let’s take the example of 12,34,567
This number is written as:
Twelve Lakh Thirty-Four Thousand Five Hundred Sixty-Seven

Now let’s place the digits:

  • 1 in the ten lakhs place

  • 2 in the lakhs place

  • 3 in the ten thousands place

  • 4 in the thousands place

  • 5 in the hundreds place

  • 6 in the tens place

  • 7 in the ones place

International Numbering System

In the International Numbering System, place values also start 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 example of 456,789,123
This number is written as:
Four Hundred Fifty-Six Million Seven Hundred Eighty-Nine Thousand One Hundred Twenty-Three

Now let’s place the digits:

  • 4 in the Hundred Million place

  • 5 in the Ten Million place

  • 6 in the Million place

  • 7 in the Hundred Thousand place

  • 8 in the Ten Thousand place

  • 9 in the Thousand place

  • 1 in the Hundreds place

  • 2 in the Tens place

  • 3 in the Ones place
