Number Names 0 to 100

Professor Greenline Explaining Math Concepts

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 0 to 100.

Number Names 0 to 100

These are the words we use to represent numbers, which makes them easier to read. Take the number 50—it is written as "Fifty." Writing numbers in words not only helps us fill out legal documents and forms, but it also improves a student's spelling skills.

There are two main ways of naming numbers: the Indian Numbering System and the International Numbering System. Understanding how numbers are named in both systems will help in effective communication and arithmetic calculations.

Now, let’s explore the two numbering systems.

Professor Greenline from BrightChamps

Indian Numbering System

In the Indian Numbering System, digits are given place values starting from the right. These include ones, tens, hundreds, and thousands, and continue to grow as the number increases.

For example, in the number 86, the digit 6 is in the ones place, and 8 is in the tens place.

The full order of place values is:
Ones → Tens → Hundreds → Thousands → Ten Thousands → Lakhs → Ten Lakhs → Crores.

Each digit in a number has a value based on its position.

Let’s take the number 56,743.
It is written in words as: Fifty-Six Thousand Seven Hundred Forty-Three.

The digits are placed as follows:

  • 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

Professor Greenline from BrightChamps

International Numbering System

Just like the Indian Numbering System, the International Numbering System also uses place value names, but they differ for larger numbers.

In this system, place values start from the right and go as follows:
Ones → Tens → Hundreds → Thousands → Ten Thousands → Hundred Thousands → Millions → Ten Millions → Hundred Millions, and so on.

Let’s take the number 743,269.
It is written in words as: Seven Hundred Forty-Three Thousand Two Hundred Sixty-Nine.

The digits are placed as follows:

  • 7 in the Hundred Thousands place

  • 4 in the Ten Thousands place

  • 3 in the Thousands place

  • 2 in the Hundreds place

  • 6 in the Tens place

  • 9 in the Ones place

Professor Greenline from BrightChamps

Rules for Writing Numbers from 0 to 100

While writing numbers from 0 to 100, there are certain rules to be followed. Below are some rules to keep in mind while writing the names of numbers.

Rule 1: Numbers from 0 to 19 have unique names. For example, 15 is written as Fifteen.

Rule 2: For numbers from 20 and above, use the tens place name followed by the ones place name. For example, 45 is written as Forty-Five.

Rule 3: Numbers like 30, 40, 50, etc., are written as Thirty, Forty, Fifty, etc., without the need for a hyphen.

Professor Greenline from BrightChamps

Tips and Tricks for Number Names 0 to 100

Always use a hyphen while writing numbers like 45 and 78. It should be written as Forty-Five and Seventy-Eight. Focus on memorizing the unique names for numbers from 0 to 19, as these do not follow the regular pattern of tens and ones. For numbers like 20, 30, 40, etc., just remember their unique names, and for numbers like 21, 22, etc., add the ones place name after the tens place name.

Common Mistakes and How to Avoid Them in Number Names 0 to 100

Students can make mistakes while learning number names. Let’s discuss a few mistakes a student can make while writing numbers from 0 to 100.

Mistake 1

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Ignoring the Hyphen

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Ignoring hyphens while writing numbers like 25 and 68 will consider the number as separate numbers. For example, 25 should be written as Twenty-Five and not Twenty Five.

Mistake 2

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Writing numbers like 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

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, 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

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Incorrect spelling

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

While writing the number names, be sure that you have written them correctly. For example, a child can write Fifteen and Fifeteen.

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 14 and 40. In 14, we have 4 in the ones place and 1 in the tens place. In 40, we have 0 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.
