The content of handwritten newspaper can write interesting mathematical knowledge.

In our concept, "1" is the smallest number, it is the beginning number of integer numbers, it is the first number of tens of thousands, yes, "1" is the first number of tens of thousands, and its position is also the most special. Let's meet this magical number with Xiaobian.

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, 1 .... The smallest one is "1", and the largest one cannot be found. If you are interested, you can look for it.

second, there is no maximum natural number.

maybe you think that you can find a maximum natural number (n), but you will find another natural number (n+1) immediately, which is greater than n. This means that the largest natural number can never be found 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 one. Some people disagree that "1" is the smallest natural number, saying that "" is smaller than "1" and "" should be the smallest natural number. This is wrong, because natural numbers refer to positive integers, and "" is the only non-positive and non-negative integer, so "" does not belong to the family of natural numbers. "1" is indeed the smallest in the family of natural numbers.

Don't underestimate the smallest "1", which is the unit of natural numbers and the first generation of natural numbers. People first know "1", and only with "1" can they get 1, 2, 3, 4 ...

I told you the special status of "1" as the first of thousands, so don't underestimate it.
