Number Names 20 to 100

These are the words that we use to represent numbers, which makes it easier to read.
Take the number 45, it is written as ‘Forty-Five’.

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

There are two different ways of naming numbers:

1. Indian Numbering System

2. International Numbering System

You need to understand how numbers are named using both numbering systems to assist 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, continuing to grow as the number increases.

For example, in the number 86, the digit 6 is in the ones place, and 8 is in the tens place.

Starting from the right, the order goes:
Ones → Tens → Hundreds → Thousands → Ten Thousands → Lakhs → Ten Lakhs → Crores

Each digit has its value based on its position in the number.

Let’s take an example of the number 9,856,743.
The number is written as:
Nine Crores Eighty-Five Lakhs Six Thousand Seven Hundred Forty-Three

The number gets placed as:
9 in the Crores place
8 in the Ten Lakhs place
5 in the Lakhs place
6 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 place 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 456,789,123.
The number is written as:
Four Hundred Fifty-Six Million Seven Hundred Eighty-Nine Thousand One Hundred Twenty-Three

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