Quick Example
Imagine you are collecting 'laddus' for a festival. If you collect 999 laddus, and then get just one more laddu, you will have exactly 1,000 laddus! It's a big, round number often used for counting many things.
Worked Example
Step-by-Step
Let's see how we reach One Thousand starting from a smaller number.
Step 1: Start with the number 990.
---
Step 2: We need to count up to 1,000. Let's add 1 to 990, which gives us 991.
---
Step 3: Keep adding 1: 991 + 1 = 992, 992 + 1 = 993, and so on.
---
Step 4: When you reach 999, add one more: 999 + 1 = 1,000.
---
Answer: So, 999 plus 1 equals 1,000.
