3 <p>Number names are a way of expressing the written form of numbers using letters. Learning number names helps you learn the basics of counting, addressing parcels, official documents, and so on. In this topic, we will learn number names from 61 to 80.</p>

4 <h2>Number Names 61 to 80</h2>

5 <p>Here is your content reformatted with proper spacing, ready to copy-paste:</p>

6 <p>These are the words that we use to represent<a>numbers</a>, which makes it easier to read. Take the number<strong>75</strong>, it is written as<strong>‘Seventy-Five’</strong>.</p>

7 <p>Writing<a>numbers in words</a>not only helps us write legal documents and fill forms, but it also helps a student's spelling skill as well.</p>

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

9 <p>Understanding how numbers are named using both numbering systems will assist in communication as well as<a>arithmetic</a>calculations.</p>

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

11 <h2>Indian Numbering System</h2>

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

13 <p>These place values include<strong>ones, tens, hundreds, and thousands</strong>, and continue to grow as the number increases.</p>

14 <p>For example, in the number<strong>73</strong>, the digit<strong>3</strong>is in the<strong>ones</strong>place, and<strong>7</strong>is in the<strong>tens</strong>place.</p>

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

16 <p>Each digit will have its value based on its position in the number.</p>

17 <p>Let’s take an example of the number<strong>62,743</strong>The number is written as<strong>Sixty-Two Thousand Seven Hundred Forty-Three</strong></p>

18 <p>The number gets placed as:<strong>6</strong>in the<strong>ten thousands</strong>place<strong>2</strong>in the<strong>thousands</strong>place<strong>7</strong>in the<strong>hundreds</strong>place<strong>4</strong>in the<strong>tens</strong>place<strong>3</strong>in the<strong>ones</strong>place</p>

19 <h2>International Numbering System</h2>

20 <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:</p>

21 <p>Ones, Tens, Hundreds, Thousands, Hundred Thousands, Millions, Ten Millions, Hundred Millions, and so on.</p>

22 <p>Let’s take the example of 74,365,269. The number is written as: Seventy-Four Million Three Hundred Sixty-Five Thousand Two Hundred Sixty-Nine</p>

23 <p>The number gets placed as: 7 in the Ten Million place 4 in the Million place 3 in the Hundred Thousands place 6 in the Ten Thousands place 5 in the Thousands place 2 in the Hundreds place 6 in the Tens place 9 in the Ones place</p>
