3 <p>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 11 to 30.</p>

4 <h2>Number Names 11 to 30</h2>

5 <p>These are the words we use to represent<a>numbers</a>, making them easier to read. Take the number<strong>15</strong>- it is written as<strong>‘Fifteen’</strong>.</p>

6 <p>Writing<a>numbers in words</a>not only helps us write legal documents and fill forms, but it also improves a student’s spelling skills.</p>

7 <p>There are two main ways<a>of</a>naming numbers:</p>

8 <ul><li><p><strong>Indian Numbering System</strong></p>

9 </li>

10 <li><p><strong>International Numbering System</strong></p>

11 </li>

12 </ul><p>Understanding both systems will help in communication and<a>arithmetic</a>calculations.</p>

13 <p>Now, let’s discuss the two numbering systems.</p>

14 <h2>Indian Numbering System</h2>

15 <p>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.</p>

16 <p>For example, in the number<strong>28</strong>, the digit<strong>8</strong>is in the ones place, and<strong>2</strong>is in the tens place.</p>

17 <p>Starting from the right, the order goes:<strong>Ones → Tens → Hundreds → Thousands → Ten Thousands → Lakhs → Ten Lakhs → Crores</strong></p>

18 <p>Each digit holds a value based on its position.</p>

19 <p>Let’s take an example of the number<strong>23</strong>. It is written as<strong>Twenty-Three</strong>.</p>

20 <p>The number gets placed as:<strong>2</strong>in the tens place<strong>3</strong>in the ones place</p>

21 <h2>International Numbering System</h2>

22 <p>Just like the Indian Numbering System, the International Numbering System also uses names, and they differ for bigger numbers. The<a>place value</a>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 27. The number is written as Twenty-Seven. The number gets placed as: 2 in the tens place 7 in the ones place</p>
