Using Commas in Indian and International Number System

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
