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.

Number Names 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.

Indian Numbering System

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

International Numbering System

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
