Notes
Using Commas in Indian and International Number System:
1. Using Commas in Indian Number System:
- Commas help using reading and writing large numbers.
- In our Indian System of Numeration we use one's, ten's, hundred's, thousand's and then lakhs and crores.
- Commas are used to mark thousands, lakhs, and crores.
- The first comma comes after hundreds of places (three digits from the right) and marks thousands. The second comma comes two digits later (five digits from the right). It comes after ten thousand places and marks lakh. The third comma comes after another two digits(seven digits from the right). It comes after ten lakh place and marks crore.
- For example,
5, 08, 01, 5923,
32, 40, 781
7, 27, 05, 062

2. Using Commas in International Number System:
- In the International System of Numeration, as it is being used we have ones, tens, hundreds, thousands, and then millions. One million is a thousand thousands.
- Commas are used to mark thousands and millions. It comes after every three digits from the right.
- The first comma marks thousands and the next comma marks millions. For example, the number 50,801,592 is read in the International System as fifty million eight hundred one thousand five hundred ninety-two. In the Indian System, it is five crores eight lakh one thousand five hundred ninety-two.
