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 1 to 30.
These are the words that we use to represent numbers, which makes it easier to read. Take the number 15, it is written as ‘Fifteen’. Writing numbers in words not only helps us write legal documents and fill forms, but it will also help a student's spelling skills as well. There are two different ways of naming numbers. They are the Indian Numbering System and the International Numbering System. You need to understand how numbers are named using both numbering systems. This will help you in communication as well as in 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, and continue to grow as the number increases. For example, in the number 18, the digit 8 is in the ones place, and 1 is in the tens place. Starting from the right, the order goes from ones to tens, hundreds, thousands, ten thousands, lakhs, ten lakhs, and crores. Each digit will have its value based on its position in the number. Let’s take an example of the number 9,543. The number gets written as Nine Thousand Five Hundred Forty-Three. The number gets placed as: 9 in the thousands place 5 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 names, and they differ for larger 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 6,543. The number is written as Six Thousand Five Hundred Forty-Three. The number gets placed as: 6 in the thousands place 5 in the hundreds place 4 in the tens place 3 in the ones place
Learning the names of the numbers from 1 to 30 using a chart will make it easy for students to write the numbers in words. List of Numbers in Words 1 to 30 The list given below shows how numbers from 1 to 30 are written using letters. Learning to write the numbers in words improves their skills in reading and writing.
While writing numbers from 1 to 30, there are certain rules to be followed. Below discussed are some rules to keep in mind while writing the names of numbers. Rule 1: Numbers 1 to 20 have unique names, such as 'One' for 1 and 'Twenty' for 20. Rule 2: For numbers 21 to 30, combine the tens and ones names. For example, 21 is written as Twenty-One.
Always use a hyphen while writing numbers like 21 and 28. It should be written as Twenty-One and Twenty-Eight. Focus on the ones place for numbers like 21, 22, and 23. After writing Twenty, just add the number: Twenty-One, Twenty-Two, Twenty-Three.
Students can make mistakes while learning number names. Let’s discuss a few mistakes a student can make while writing numbers from 1 to 30.
What is the sum of 7 + 10 in words?
Seventeen
First, we need to find the sum 7 + 10. The sum is 17 → 7 + 10 = 17. We write 17 in words as Seventeen.
What is the difference of 30 - 5 in words?
Twenty-Five
We need to find the difference between 30 and 5. The difference is 25 → 30 - 5 = 25. Therefore, we write the answer as Twenty-Five.
Find the product of 5 and 3. Write the result in words.
Fifteen
The product is 15 → 5 × 3 = 15. Hence, 15 in words is Fifteen.
What is (20 ÷ 4) + 5 in words?
Ten
((20 ÷ 4) + 5) = 5 + 5 = 10. We find the final result as 10. Therefore, 10 is written as Ten.
What is the product of 2 and 11 in words?
Twenty-Two
The product of 2 and 11 is 22 → 2 × 11 = 22. So, 22 in words is Twenty-Two.
