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 31 to 40.</p>

4 <h2>Number Names 31 to 40</h2>

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

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

7 <p>There are two different 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 how numbers are named using both systems will help in<strong>communication</strong>as well as in<strong><a>arithmetic</a>calculations</strong>.</p>

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

14 <h2>Indian Numbering System</h2>

15 <p>In the<strong>Indian Numbering System</strong>, digits are assigned<strong>place values</strong>starting from the<strong>right</strong>. These place values include:</p>

16 <p><strong>Ones → Tens → Hundreds → Thousands → Ten Thousands → Lakhs → Ten Lakhs → Crores</strong></p>

17 <p>Each digit in a number has a value based on its<strong>position</strong>.</p>

18 <p>For example, in the number<strong>36</strong>:</p>

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

20 </li>

21 <li><p>3 is in the<strong>tens</strong>place</p>

22 </li>

23 </ul><p>Let’s take a larger number:<strong>9,56,28,743</strong>It is written as:<strong>Nine Crore Fifty-Six Lakhs Twenty-Eight Thousand Seven Hundred Forty-Three</strong></p>

24 <p>The number gets placed as:</p>

25 <ul><li><p>9 in the<strong>crores</strong>place</p>

26 </li>

27 <li><p>5 in the<strong>ten lakhs</strong>place</p>

28 </li>

29 <li><p>6 in the<strong>lakhs</strong>place</p>

30 </li>

31 <li><p>2 in the<strong>ten thousands</strong>place</p>

32 </li>

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

34 </li>

35 <li><p>7 in the<strong>hundreds</strong>place</p>

36 </li>

37 <li><p>4 in the<strong>tens</strong>place</p>

38 </li>

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

40 </li>

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

42 <p>Just like the<strong>Indian Numbering System</strong>, the<strong>International Numbering System</strong>also uses<strong>place names</strong>, but they differ for<strong>larger numbers</strong>.</p>

43 <p>The<strong><a>place value</a></strong>starts from the<strong>right</strong>and follows this order:<strong>Ones → Tens → Hundreds → Thousands → Ten Thousands → Hundred Thousands → Millions → Ten Millions → Hundred Millions</strong>, and so on.</p>

44 <p>Let’s take the example of<strong>74,385,629</strong>It is written as:<strong>Seventy-Four Million Three Hundred Eighty-Five Thousand Six Hundred Twenty-Nine</strong></p>

45 <p>The number gets placed as:</p>

46 <ul><li><p>7 in the<strong>Ten Million</strong>place</p>

47 </li>

48 <li><p>4 in the<strong>Million</strong>place</p>

49 </li>

50 <li><p>3 in the<strong>Hundred Thousands</strong>place</p>

51 </li>

52 <li><p>8 in the<strong>Ten Thousands</strong>place</p>

53 </li>

54 <li><p>5 in the<strong>Thousands</strong>place</p>

55 </li>

56 <li><p>6 in the<strong>Hundreds</strong>place</p>

57 </li>

58 <li><p>2 in the<strong>Tens</strong>place</p>

59 </li>

60 <li><p>9 in the<strong>Ones</strong>place</p>

61 </li>
