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 30 to 40.</p>

4 <h2>Number Names 30 to 40</h2>

5 <p>These are the words that we use to represent<a>numbers</a>, which makes it easier to read. Take the number<strong>35</strong>, it is written as<strong>‘Thirty-Five’</strong>. 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>

6 <p>There are two different ways of naming numbers:<strong>The Indian Numbering System</strong>and<strong>the International Numbering System</strong>.</p>

7 <p>You need to understand how numbers are named using both numbering systems. This will help you in communication as well as in<a>arithmetic</a>calculations.</p>

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

9 <h2>Indian Numbering System</h2>

10 <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>

11 <p>For example, in the number<strong>36</strong>, the digit<strong>6</strong>is in the ones place, and<strong>3</strong>is in the tens place.</p>

12 <p>Starting from the right, the order goes from:<strong>ones → tens → hundreds → thousands → ten thousands → lakhs → ten lakhs → crores</strong></p>

13 <p>Each digit has its value based on its position in the number.</p>

14 <p>Let’s take an example of the number<strong>9,56,28,743</strong>The number is written as:<strong>Nine Crore Fifty-Six Lakhs Twenty-Eight Thousand Seven Hundred Forty-Three</strong></p>

15 <p>The digits are placed as:<strong>9</strong>in the crores place<strong>5</strong>in the ten lakhs place<strong>6</strong>in the lakhs place<strong>2</strong>in the ten thousands place<strong>8</strong>in the thousands place<strong>7</strong>in the hundreds place<strong>4</strong>in the tens place<strong>3</strong>in the ones place</p>

16 <h2>International Numbering System</h2>

17 <p>Just like the Indian Numbering System, the International Numbering System also uses names, but they differ for larger numbers. In this system,<strong>place values start from the right</strong>and go in groups of three digits as you move to the left.</p>

18 <p>The place values are:<strong>Ones → Tens → Hundreds → Thousands → Ten Thousands → Hundred Thousands → Millions → Ten Millions → Hundred Millions</strong>, and so on.</p>

19 <p>Let’s take the example of the number<strong>743,856,269</strong>. It is written as:<strong>Seven Hundred Forty-Three Million Eight Hundred Fifty-Six Thousand Two Hundred Sixty-Nine</strong></p>

20 <p>The digits are placed as:<strong>7</strong>in the Hundred Millions place<strong>4</strong>in the Ten Millions place<strong>3</strong>in the Millions place<strong>8</strong>in the Hundred Thousands place<strong>5</strong>in the Ten Thousands place<strong>6</strong>in the Thousands place<strong>2</strong>in the Hundreds place<strong>6</strong>in the Tens place<strong>9</strong>in the Ones place</p>
