Number Names 41 to 50

These are the words that we use to represent numbers, which makes it easier to read. Take the number 45, it is written as ‘Forty-Five’. Writing numbers in words not only helps us write legal documents and fill forms, but it also helps a student's spelling skills 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 48, the digit 8 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 the example of the number 56,789 The number gets written as Fifty-Six Thousand Seven Hundred Eighty-Nine. The number gets placed as: 5 in the ten thousands place 6 in the thousands place 7 in the hundreds place 8 in the tens place 9 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 123,456,789, The number is written as One Hundred Twenty-Three Million Four Hundred Fifty-Six Thousand Seven Hundred Eighty-Nine. The number gets placed as: 1 in the Hundred Million place 2 in the Ten Million place 3 in the Million place 4 in the Hundred Thousands place 5 in the Ten Thousands place 6 in the Thousands place 7 in the Hundreds place 8 in the Tens place 9 in the Ones place

Writing Fifty Zero instead of Fifty

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Students might get confused between Fifty Zero and Fifty for 50. The correct way to express 50 in words is Fifty. There’s no need to write zero after fifty.

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, 48 is written as Forty and Eight. But in American English, we do not use ‘and’. The number 48 in American English is written as Forty-Eight. 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 41 and 14. In 41, we have 1 in the ones place and 4 in the tens place. In 14, we have 4 in the ones place and 1 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.
