A thousand is a number that comes after 999. It is the smallest four-digit number. We write a thousand as '1,000' or '1000'.
Simple Example
Quick Example
Imagine you have 10 packets of biscuits, and each packet has 100 biscuits. If you count all the biscuits together, you will have 1000 biscuits. That's a thousand!
Worked Example
Step-by-Step
Let's see how we reach a thousand by counting.
Step 1: Start with 999.
---Step 2: Add 1 to 999. (999 + 1)
---Step 3: When you add 1 to 9, it becomes 10. So, the last digit becomes 0, and you carry over 1 to the tens place.
---Step 4: Now, in the tens place, you have 9 + 1 (carried over) = 10. So, the tens digit becomes 0, and you carry over 1 to the hundreds place.
---Step 5: In the hundreds place, you have 9 + 1 (carried over) = 10. So, the hundreds digit becomes 0, and you carry over 1 to the thousands place.
---Step 6: In the thousands place, you now have 1.
---Step 7: Putting it all together, 999 + 1 = 1000.
---Answer: 1000 is a thousand.
Why It Matters

Common Mistakes
MISTAKE: Writing 100 for a thousand | CORRECTION: A thousand has three zeros after the 1, so it's 1,000, not 100.
MISTAKE: Confusing a thousand with a hundred or ten thousand | CORRECTION: A thousand (1,000) has 3 zeros, a hundred (100) has 2 zeros, and ten thousand (10,000) has 4 zeros. Count the zeros carefully!
MISTAKE: Not using a comma in 1,000 | CORRECTION: While 1000 is also correct, using a comma (1,000) helps read large numbers easily, especially in India where we use the Indian numbering system (lakh, crore).
