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 80 to 100.</p>

4 <h2>Number Names 80 to 100</h2>

5 <p>These are the words that we use to represent<a>numbers</a>, which makes it easier to read. Take the number 85, it is written as ‘Eighty-Five’. Writing<a>numbers in words</a>not only helps us write legal documents and fill forms, but it also helps improve a student's spelling skills.</p>

6 <p>There are two different ways of naming numbers: the Indian Numbering System and the International Numbering System. Understanding how numbers are named using both systems will help you in communication and<a>arithmetic</a>calculations.</p>

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

8 <h2>Indian Numbering System</h2>

9 <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>

10 <p>For example, in the number 86, the digit 6 is in the ones place, and 8 is in the tens place. Starting from the right, the order goes from ones to tens, hundreds, thousands, ten thousands, lakhs, ten lakhs, and crores. Each digit will have its value based on its position in the number.</p>

11 <p>Let’s take an example of the number 96,428. The number is written as Ninety-Six Thousand Four Hundred Twenty-Eight.</p>

12 <p>The number is placed as: 9 in the ten thousands place 6 in the thousands place 4 in the hundreds place 2 in the tens place 8 in the ones place</p>

13 <h2>International Numbering System</h2>

14 <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.</p>

15 <p>The place values are ones, tens, hundreds, thousands, hundred thousands, millions, ten millions, hundred millions, and so on.</p>

16 <p>Let’s take the example of 85,471. The number is written as Eighty-Five Thousand Four Hundred Seventy-One.</p>

17 <p>The number is placed as: 8 in the Ten Thousands place 5 in the Thousands place 4 in the Hundreds place 7 in the Tens place 1 in the Ones place</p>
