What to Focus On

  • Numeral: Symbol used to write a number (e.g., 7).
  • Numeration: Writing a number in words (e.g., seven).
  • Two main systems: Indian and International.
  • Periods: Ones, Thousands, Lakhs, Crores.
  • Commas: After 3 digits, then after every 2 digits (e.g., 1,00,000).
  • 1 lakh = 1,00,000 (6 digits).
  • Periods: Ones, Thousands, Millions, Billions.
  • Commas: After every 3 digits (e.g., 1,000,000).
  • 1 million = 1,000,000 (7 digits).

Common Mistakes to Avoid

Students think the number of digits determines the period name in both systems.

Commas are placed every three digits from right in both systems.

1 crore equals 1 billion in the International system.
