Number Names 20 to 30

These are the words that we use to represent numbers, which makes it easier to read. Take the number 25, it is written as ‘Twenty-Five’. Writing numbers in words not only helps us write legal documents and fill forms, but it also improves a student's spelling skills. There are two different ways of naming numbers. They are the Indian Numbering System and the International Numbering System. Understanding both numbering systems will assist in communication and arithmetic calculations. Now let's discuss the two numbering systems.

Professor Greenline from BrightChamps

Indian Numbering System

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. For example, in the number 28, the digit 8 is in the ones place, and 2 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. Let's take an example of the number 29,743. The number gets written as Twenty-Nine Thousand Seven Hundred Forty-Three. The number gets placed as: 2 in the ten thousands place 9 in the thousands place 7 in the hundreds place 4 in the tens place 3 in the ones place

International Numbering System

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 2,743,856. The number is written as Two Million Seven Hundred Forty-Three Thousand Eight Hundred Fifty-Six. The number gets placed as: 2 in the Million place 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

Ignoring hyphens while writing numbers like 26 and 29 will consider the number as separate numbers. For example, 26 should be written as Twenty-Six and not Twenty Six.

Mistake 2

Writing Thirty Zero instead of Thirty

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Students might get confused between Thirty Zero and Thirty for 30. The correct way to express 30 in words is Thirty. There's no need to write zero after thirty.

Mistake 3

Using 'and' while writing number names in American English

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

We use 'and' while writing number names only in British English. For example, 21 is written as Twenty and One. But in American English, we do not use 'and'. The number 21 in American English is written as Twenty-One. Always make sure that students are aware of the difference.

Mistake 4

Mistake 5

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Getting confused with the tens and ones place

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Students can get confused between numbers like 24 and 42. In 24, we have 4 in the ones place and 2 in the tens place. In 42, we have 2 in the ones place and 4 in the tens place. To avoid these, students need to learn how to pronounce the numbers correctly. Once they learn to pronounce the numbers, they can write the number names correctly.
