Class 6 Maths Knowing Our Numbers Using Commas

Using Commas

Commas are used while reading and writing large numbers. In Indian System of Numeration, Commas are used to mark thousands, lakhs and crores.

  • The first comma comes after hundreds place (three digits from the right) and marks thousands.
  • The second comma comes two digits later (five digits from the right). It comes after ten thousands place 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 eg. 68537954 can be written as 6,85,37,954.
