I understand that big numbers like million, billion, and trillion can be confusing. Here's a simple way to think about them:
- Million is like adding one more thousand to 1,000, so it's 1,000,000.
- Billion is like adding two more thousands to 1,000, so it's 1,000,000,000.
A trillion is like adding three more thousand to 1,000, so it's 1,000,000,000,000.
In India, we have a different way of writing these numbers:
- 1 Million is written as 10,00,000, which is also called 10 lakhs.
- 1 Billion is written as 1,00,00,00,000, which is also called 100 crore.
- 1 Trillion is written as 10,00,00,00,00,000, which is also called 100,000 crore.

Here's a quick way to remember the order: K (Thousand), M (Million), B (Billion), T (Trillion), or you can think of it as Thousand, Million, Billion, Trillion. I hope this makes it easy to understand.
And remember, 1 billion rupees and 1 billion dollars are not the same. You need to use the conversion rate to find the equivalent in your currency. Currently, 1 USD is equal to Rs. 83.28, so 1 Billion USD is 83.28 times 100 crore, which is 8328 crore.
