What to Focus On

  • 10 ten thousands = 1 Lakh (1,00,000)
  • Smallest 6-digit number: 1,00,000
  • Largest 6-digit number: 9,99,999

  • Indian system uses: Ones, Thousands, Lakhs, Crores
  • International system uses: Ones, Thousands, Millions
  • Commas help in reading large numbers easily

  • Place value depends on the digit's position
  • Period is the group (like Ones, Thousands) the digit belongs to

Common Mistakes to Avoid

The largest number is always the one with the biggest digit at the start.

Commas in numbers are just for decoration and don't affect the value.

Zero can be placed at the beginning of a number.

Memory Tips

10 ones = 1 Ten, 10 tens = 1 Hundred, 10 hundreds = 1 Thousand

10 ten thousands = 1 Lakh (1,00,000)

1 Lakh = 100,000; 10 Lakh = 1,000,000; 1 Crore = 1,00,00,000

Indian Number System periods: Ones, Thousands, Lakhs, Crores
