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 21 to 50.</p>

4 <h2>Number Names 21 to 50</h2>

5 <p>These are the words we use to represent<a>numbers</a>, making them easier to read and understand. Take the number<strong>25</strong>- it is written as<strong>‘Twenty-Five’</strong>.</p>

6 <p>Writing<a>numbers in words</a>not only helps us with<strong>legal documents</strong>and<strong>form-filling</strong>, but it also improves a student's<strong>spelling skills</strong>.</p>

7 <p>There are two main ways of 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 how numbers are named in both systems will help in<strong>communication</strong>and<strong><a>arithmetic</a>calculations</strong>. Let’s now explore both numbering systems.</p>

13 <h2>Indian Numbering System</h2>

14 <p>In the<strong>Indian Numbering System</strong>, digits are assigned<strong>place values</strong>starting from the<strong>right</strong>. These include<strong>ones</strong>,<strong>tens</strong>,<strong>hundreds</strong>,<strong>thousands</strong>, and continue to grow as the number increases.</p>

15 <p>For example, in the number<strong>46</strong>,</p>

16 <ul><li><p>6 is in the<strong>ones place</strong></p>

17 </li>

18 <li><p>4 is in the<strong>tens place</strong></p>

19 </li>

20 </ul><p>The full order of place values is:<strong>Ones → Tens → Hundreds → Thousands → Ten Thousands → Lakhs → Ten Lakhs → Crores</strong></p>

21 <p>Each digit gets its value based on its<strong>position</strong>.</p>

22 <p>Let’s take the number<strong>48,273</strong>. It is written in words as:<strong>Forty-Eight Thousand Two Hundred Seventy-Three</strong></p>

23 <p>Its<a>place value</a>breakdown is:</p>

24 <ul><li><p>4 in the<strong>ten thousands</strong>place</p>

25 </li>

26 <li><p>8 in the<strong>thousands</strong>place</p>

27 </li>

28 <li><p>2 in the<strong>hundreds</strong>place</p>

29 </li>

30 <li><p>7 in the<strong>tens</strong>place</p>

31 </li>

32 <li><p>3 in the<strong>ones</strong>place</p>

33 </li>

34 </ul><h2>International Numbering System</h2>

35 <p>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 ones, tens, hundreds, thousands, hundred thousands, millions, ten millions, hundred millions, and so on. Let’s take the example of 743,856. The number is written as Seven Hundred Forty-Three Thousand Eight Hundred Fifty-Six. The number gets placed as: 7 in the Hundred Thousands place 4 in the Ten Thousands place 3 in the Thousands place 8 in the Hundreds place 5 in the Tens place 6 in the Ones place</p>
