For Indian System of Numeration:

Placing Commas:
- Start from the rightmost digit.
- Place the first comma after three digits.
- Then place commas after every two digits.
- Example: 1,23,45,678
Reading and Writing Numbers:
- Identify place values: Ones, Tens, Hundreds, Thousands, Ten-Thousands, Lakhs, Ten-Lakhs, Crores.
- Convert word form to numeral by adding place values.
- Convert numeral to word form by breaking into place values using commas.
Example Conversion:
- "15 crore 96 lakh 3500" → 15,96,00,3500 (with correct commas and place values).
- Expanded form can be used for clarity but is optional.

For International System of Numeration:
