Number names are a way of expressing the written form of numbers using letters. Learning number names will help you learn the basics of counting, addressing parcels, official documents, and so on. In this topic, we will learn number names from 0 to 100.
These are the words we use to represent numbers, which makes them easier to read. Take the number 50—it is written as "Fifty." Writing numbers in words not only helps us fill out legal documents and forms, but it also improves a student's spelling skills.
There are two main ways of naming numbers: the Indian Numbering System and the International Numbering System. Understanding how numbers are named in both systems will help in effective communication and arithmetic calculations.
Now, let’s explore the two numbering systems.
In the Indian Numbering System, digits are given place values starting from the right. These include ones, tens, hundreds, and thousands, and continue 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.
The full order of place values is:
Ones → Tens → Hundreds → Thousands → Ten Thousands → Lakhs → Ten Lakhs → Crores.
Each digit in a number has a value based on its position.
Let’s take the number 56,743.
It is written in words as: Fifty-Six Thousand Seven Hundred Forty-Three.
The digits are placed as follows:
5 in the Ten Thousands 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 value names, but they differ for larger numbers.
In this system, place values start from the right and go as follows:
Ones → Tens → Hundreds → Thousands → Ten Thousands → Hundred Thousands → Millions → Ten Millions → Hundred Millions, and so on.
Let’s take the number 743,269.
It is written in words as: Seven Hundred Forty-Three Thousand Two Hundred Sixty-Nine.
The digits are placed as follows:
7 in the Hundred Thousands place
4 in the Ten Thousands place
3 in the Thousands place
2 in the Hundreds place
6 in the Tens place
9 in the Ones place
Learning the names of the numbers from 0 to 100 using a chart will make it easy for the students to write the numbers in words. List of Numbers in Words 0 to 100
The list given below shows how numbers from 0 to 100 are written using letters. Learning to write the numbers in words improves their skills in reading and writing.
While writing numbers from 0 to 100, there are certain rules to be followed. Below are some rules to keep in mind while writing the names of numbers.
Rule 1: Numbers from 0 to 19 have unique names. For example, 15 is written as Fifteen.
Rule 2: For numbers from 20 and above, use the tens place name followed by the ones place name. For example, 45 is written as Forty-Five.
Rule 3: Numbers like 30, 40, 50, etc., are written as Thirty, Forty, Fifty, etc., without the need for a hyphen.
Always use a hyphen while writing numbers like 45 and 78. It should be written as Forty-Five and Seventy-Eight. Focus on memorizing the unique names for numbers from 0 to 19, as these do not follow the regular pattern of tens and ones. For numbers like 20, 30, 40, etc., just remember their unique names, and for numbers like 21, 22, etc., add the ones place name after the tens place name.
Students can make mistakes while learning number names. Let’s discuss a few mistakes a student can make while writing numbers from 0 to 100.
What is the sum of 8 + 10 in words?
Eighteen
First, we need to find the sum 8 + 10
The sum is 18 → 8 + 10 = 18
We write 18 in words as Eighteen
What is the difference of 100 - 30 in words?
Seventy
We need to find the difference between 100 and 30
The difference is 70 → 100 - 30 = 70
Therefore, we write the answer as Seventy
Find the product of 5 and 4. Write the result in words
Twenty
The product is 20 → 5 × 4 = 20
Hence, 20 in words is Twenty
What is (50 ÷ 2) + 10 in words
Thirty-Five
((50 ÷ 2) + 10) = 25 + 10 = 35
We find the final result as 35.
Therefore, 35 is written as Thirty-Five
What is the product of 2 and 49 in words?
Ninety-Eight
The product of 2 and 49 is 98 → 2 × 49 = 98
So, 98 in words is Ninety-Eight
Place Value refers to the value a digit holds based on its position in a number (e.g., in 23, 3 is in the ones place and 2 is in the tens place).
Number Form is the numeric version of a number written in words (e.g., Forty-Four → 44).
The International Numbering System is the global format for writing large numbers using terms like thousand, million, and billion instead of lakh and crore.
A Hyphen is a punctuation mark used to join tens and ones in number names (e.g., Fifty-Four).
Unique Names are special number words that don't follow regular patterns, such as Eleven, Twelve, and Thirteen.
