Good morning, children. Now you know how to count up to ten thousand. Let's learn more about counting. The smallest single digit number is 1, and the greatest single digit number is 9. Now, let's set 1 to 9. What do we get? It is equal to 10, so we get 10, which is the smallest two-digit number. The greatest two-digit number can be formed by using the greatest digit, which is nine. So, for a two-digit number, use 9 two times. We get 99. And what is 99 plus 1? It is equal to 100. So, we get the smallest three-digit number, which is 100. If we keep going like this, the greatest three-digit number has to be three times 9 written, so 999. Now, again, if we add 1 to it, what should we get? We should get the smallest four-digit number. Let's add 9 plus 1. Carry over 1. Again, 9 plus carry over 10. Again, 9 plus carry over 10. So, we get 1,000. As we said, 1,000 is the smallest four-digit number. Continuing, the greatest four-digit number has to be nine times nine written, so 9,999. Now, let's add 1 to it. Let's see. 9,999 plus 1 is equal to 10,000. 9 plus 1 is 10, carry over 1. Here, adding 9 plus 1, again, we get 10. So, 1 is carry over. Again, 9 plus 1 is 10. Here, 1 is carry over. 9 plus 1 is 10. Here, carry over. And lastly, 9 plus 1 is equal to 10. Now, which number is this? It has six digits. It is the smallest six-digit number. And what do we call it? 1, 0, 0, 0, 0, 0. It has six zeros, so it is equal to one hundred thousand. And what is it called...
