Simple Example

Quick Example

Imagine you are counting all the 'laddoos' made for a big festival in your town. If you count 1000 'laddoos', then 2000, and so on, when you reach 9999 'laddoos' and add just one more, you get 10000 'laddoos'. It's a very big number of sweets!

Worked Example

Step-by-Step

Let's see how 10000 is formed by adding:---Step 1: Start with the largest four-digit number, which is 9999.---Step 2: Add 1 to this number. So, we have 9999 + 1.---Step 3: When you add 1 to the 'ones' place (9 + 1 = 10), you carry over 1 to the 'tens' place.---Step 4: This continues, carrying over to the 'hundreds' and 'thousands' places. 9999 + 1 = 10000.---Answer: The number 10000 is formed by adding 1 to 9999.
