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 100 to 10000.
These are the words that we use to represent numbers, making them easier to read and understand.
For example, the number 1050 is written as ‘One Thousand Fifty’.
Writing numbers in words not only helps with tasks like filling out legal documents and forms 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 is important, as it helps with clear communication, especially when reading or writing large numbers, and supports accuracy in arithmetic.
Let’s now take a closer look at each of these numbering systems.
In the Indian Numbering System, digits are given specific place values starting from the right. These place values help us understand the value of each digit in a number. The common place values are:
Ones, Tens, Hundreds, Thousands, Ten Thousands, Lakhs, Ten Lakhs, and Crores.
For example, take the number 1860:
0 is in the ones place
6 is in the tens place
8 is in the hundreds place
1 is in the thousands place
Now, let’s look at a bigger number: 9,56,28,743
This is written in words as:
Nine Crore Fifty-Six Lakhs Twenty-Eight Thousand Seven Hundred Forty-Three
Here's how the digits are placed:
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
Understanding these place values helps in reading, writing, and performing arithmetic operations correctly using the Indian system.
In the International Numbering System, place values also start from the right, but they differ from the Indian system for larger numbers. The place values grow as follows:
Ones, Tens, Hundreds, Thousands, Ten Thousands, Hundred Thousands, Millions, Ten Millions, Hundred Millions, and so on.
Let’s take the example of the number 743,856,269.
This number is written in words as:
Seven Hundred Forty-Three Million Eight Hundred Fifty-Six Thousand Two Hundred Sixty-Nine
Now let’s break it down by place value:
7 is in the Hundred Millions place
4 is in the Ten Millions place
3 is in the Millions place
8 is in the Hundred Thousands place
5 is in the Ten Thousands place
6 is in the Thousands place
2 is in the Hundreds place
6 is in the Tens place
9 is in the Ones place
Understanding the International Numbering System is especially useful in global communication, finance, and when dealing with international data.
Learning the names of the numbers from 100 to 10000 using a chart will make it easy for students to write the numbers in words. List of Numbers in Words 100 to 10000 The list given below shows how numbers from 100 to 10000 are written using letters. Learning to write the numbers in words improves skills in reading and writing.
Here’s a clear explanation of the rules to follow when writing number names from 100 to 10,000:
Rule 1: Use “Hundred” for numbers from 100 to 999
When a number is in the hundreds range, start naming it with the hundreds digit followed by the word “Hundred.”
Example:
150 → One Hundred Fifty
375 → Three Hundred Seventy-Five
Rule 2: Use “Thousand” for numbers from 1000 onwards
When a number crosses 1000, start with the thousands digit(s), followed by the rest of the number.
Example:
1001 → One Thousand One
1025 → One Thousand Twenty-Five
Rule 3: Recognize and follow the number pattern
Larger numbers still follow the place value pattern of thousands, hundreds, tens, and ones.
Example:
1450 → One Thousand Four Hundred Fifty
1680 → One Thousand Six Hundred Eighty
1720 → One Thousand Seven Hundred Twenty
Understanding these rules helps in accurately writing and reading number names, especially when working with forms, documents, or math problems.
Always use a hyphen while writing numbers like 1455 and 1788. It should be written as One Thousand Four Hundred Fifty-Five and One Thousand Seven Hundred Eighty-Eight. Always keep writing the numbers with ‘Hundred’ and ‘Thousand’, as in One Hundred for 100 and One Thousand for 1000. Always focus on the tens place for numbers like 1100, 1200, 1300, etc. After writing One Thousand, you just need to add the number. These numbers can be written as One Thousand One Hundred, One Thousand Two Hundred, and One Thousand Three Hundred.
Students can make mistakes while learning number names. Let’s discuss a few mistakes a student can make while writing numbers from 100 to 10000.
What is the sum of 1850 + 100 in words?
One Thousand Nine Hundred Fifty
First, we need to find the sum 1850 + 100
The sum is 1950 → 1850 + 100 = 1950
We write 1950 in words as One Thousand Nine Hundred Fifty
What is the difference of 10000 - 900 in words?
Nine Thousand One Hundred
We need to find the difference between 10000 and 900
The difference is 9100 → 10000 - 900 = 9100
Therefore, we write the answer as Nine Thousand One Hundred
Find the product of 200 and 5. Write the result in words
One Thousand
The product is 1000 → 200 × 5 = 1000
Hence, 1000 in words is One Thousand.
What is (5000 ÷ 2) + 150 in words
Two Thousand Six Hundred Fifty
((5000 ÷ 2) + 150) = 2500 + 150 = 2650
We find the final result as 2650.
Therefore, 2650 is written as Two Thousand Six Hundred Fifty
What is the product of 20 and 49 in words?
Nine Hundred Eighty
The product of 20 and 49 is 980 → 20 × 49 = 980
So, 980 in words is Nine Hundred Eighty
