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 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.
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
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

While writing numbers from 31 to 50, there are certain rules to be followed. Below discussed are some rules to keep in mind while writing the names of numbers.

Rule 2: For numbers starting with 40, use “Forty.” For example, 41 is written as “Forty-One.”
Rule 3: Numbers follow a pattern. For example, 33 is written as Thirty-Three, 47 is written as Forty-Seven, and 49 is written as Forty-Nine.
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.
