Practice and Revision - Numbers in India and International System
Let us practise and revise what we learned about numbers in india and international system. India uses a numbering system with lakhs and cro
Core concept
In the Indian system, we group numbers as ones, tens, hundreds, thousands, lakhs (1,00,000), and crores (1,00,00,000).
How it works
In the international system, we group as ones, tens, hundreds, thousands, millions (1,000,000), and billions (1,000,000,000).
Why it matters
The same large number can be written differently in each system - for example, 10,000,000 (international) equals 1,00,00,000 or 1 crore (Indian).
Key detail
Understanding both systems helps us read and compare numbers correctly, especially when dealing with international information.
