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 40.

Number Names 1 to 40

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 also helps improve a student's spelling skills. There are two different ways of naming numbers: the Indian Numbering System and the International Numbering System. Understanding how numbers are named using both numbering systems will help in communication as well as 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 28, the digit 8 is in the ones place, and 2 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 3,456 The number gets written as Three Thousand Four Hundred Fifty-Six. The number gets placed as: 3 in the thousands place 4 in the hundreds place 5 in the tens place 6 in the ones place

International Numbering System

Just like the Indian Numbering System, the International Numbering System also uses names, and they differ for bigger numbers. The place value starts from the right. The place values are one, tens, hundreds, thousands, hundred thousands, millions, ten millions, hundred millions, and so on. Let’s take the example of 1,234 The number is written as One Thousand Two Hundred Thirty-Four. The number gets placed as: 1 in the Thousand place 2 in the Hundred place 3 in the Ten place 4 in the One place
