Professor Greenline Explaining Math Concepts

Number Names 31 to 50

These are the words that we use to represent numbers, which makes it easier to read. Take the number 35, it is written as ‘Thirty-Five’. Writing numbers in words not only helps us write legal documents, fill forms, but it will also help a student's spelling skill as well. There are two different ways of naming numbers. They are the Indian Numbering System and the International Numbering System. You need to understand how numbers are named using both numbering systems. This will help you in communication as well as in 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 46, the digit 6 is in the ones place, and 4 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 9,56,743

The number gets written as Nine Lakh Fifty-Six Thousand Seven Hundred Forty-Three.

The number gets placed as:

9 in the lakhs place

5 in the ten thousands place

6 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 743,826.
The number is written as:
Seven Hundred Forty-Three Thousand Eight Hundred Twenty-Six

The number gets placed as:
7 in the Hundred Thousands place
4 in the Ten Thousands place
3 in the Thousands place
8 in the Hundreds place
2 in the Tens place
6 in the Ones place

Tips and Tricks for Number Names 31 to 50

Always use a hyphen while writing numbers like 35 and 48. It should be written as Thirty-Five and Forty-Eight. Always keep writing the numbers with ‘Thirty’ and ‘Forty’, as in Thirty for 30 to 39 and Forty for 40 to 49.

 

Always focus on the tens place for numbers like 31, 42, 50, etc. After writing Thirty or Forty, you just need to add the number, that's it. The mentioned numbers can be written as Thirty-One, Forty-Two, and Fifty.

Ignoring hyphens while writing numbers like 32 and 48 will consider the number as separate numbers. For example, 32 should be written as Thirty-Two and not Thirty Two.

Mistake 2

Writing Forty Zero instead of Forty

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Students might get confused between Forty Zero and Forty for 40. The correct way to express 40 in words is Forty. There’s no need to write zero after forty.

Mistake 3

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

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, 44 is written as Forty and Four. But in American English, we do not use ‘and’. The number 44 in American English is written as Forty-Four. Always make sure that students are aware of the difference.

Mistake 4

Incorrect spelling

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

While writing the number names, be sure that you have written it correctly. For example, a child can write Thirty-Five and Therty-Five.

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 34 and 43. In 34, we have 4 in the ones place and 3 in the tens place. In 43, we have 3 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.
