What Are Indian Numerals from 1 to 10?
Jagat owns a huge farm.
He sold his entire wheat harvest for Rs. 384756182.
Let us try to read this big number, "384756182", using the Indian numeral system.
First, we will place it in the Indian place value chart.
Starting from the right-most number, this number represents the ones digit.
It is easy to read any large number if we place the number in the place value chart of the Indian numeral system.
Therefore, the number is "Thirty eight crore forty seven lakh fifty six thousand one hundred and eighty two".
Let us see how the 6 and 7 digits numbers are written in the Indian Numeral System.
What Is the Difference between Indian Numeral System and International Numeral System?
The International numeral system is used worldwide.
This is Aaron.
He says that he has bought a house for 4 million rupees.
But, how much is one million?
Let us see.
When we count in terms of ones, hundreds, thousands, ten thousands, hundred thousands, millions and billions, then we are referring to the International numeral system.
The following table shows the periods, places, and digits in a number for the International numeral system.
Thus, in one million, there are 6 zeros and 7 digits.
Now, let's learn to read and write a number using the International numeral system.
We will write the numbers in the standard form using commas and read the numbers using periods.
For example:Rewrite the number \(1347823\) in the International numeral system using commas.
How will you read this number?
In the International numeral system, we begin from the right and insert commas after every three digits.
We divide the number in periods and read the period separately.
Standard Form: \(1,347,823\)
Number Name: One million three hundred forty seven thousand eight hundred and twenty three.
Thus, the main difference in Indian and international numeration system is the placement of the commas.
Let us solve a few examples to understand the Indian numeral system.
Rewrite the number 2687393 by placing the comma as per the Indian numeral system.
In the Indian numeral system, we use commas to mark thousands, lakhs and crores.
We insert a comma after each period.
Starting from the right side of the number, the first comma is inserted after the hundreds digit.
The second comma is inserted after the thousands period, that is after 2 places from the first comma.
The third comma is inserted after the lakhs period.
This is how we insert the commas in the Indian numeral system.
How will the number 2,34,32,829 be read out according to the Indian numeral system?
The number 2,34,32,829 will be read as "Two crore thirty four lakh thirty two thousand eight hundred and twenty nine".
