First, the smallest number.
The ancient and huge family of natural numbers is composed of all natural numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and so on. The smallest one is "1", and the largest one can't be found. You can look for it if you are interested.
Second, there is no maximum natural number.
Maybe you think you can find a largest natural number (n), but you will immediately find another natural number (n+ 1) greater than n, which means that you will never find the largest natural number in the family of natural numbers.
Third, "1" is indeed the smallest in the family of natural numbers.
The natural number is infinite, and "1" is the smallest of the natural numbers. Some people disagree that "1" is the smallest natural number, saying that "0" is smaller than "1" and "0" should be the smallest natural number. This is wrong, because natural numbers refer to positive integers, and "0" is the only non-positive non-negative integer, so "0" does not belong to the family of natural numbers. "1" is indeed the smallest in the family of natural numbers.
Fourth, where is the one yuan?
Three people stayed in a hotel, and the price per person per day was 10 yuan. Everyone paid 10 yuan, and the total was the boss 30 yuan. Later, the boss gave a discount of 5 yuan and asked the waiter to return it to them. As a result, the waiter embezzled 2 yuan, and each of the remaining 3 yuan returned 1 yuan, which means that each person spent 9 yuan's money. Three people spent a total of * * * 27 yuan, plus 2 yuan, a corrupt waiter, spent a total of * * * 29 yuan. Where did the dollar go?
