Draw a mathematical handwritten newspaper, the content of which can be mathematician stories, mathematical puzzles and interesting mathematical problems.

The content of handwritten newspaper can write interesting mathematical knowledge.

In our concept, "1" is the smallest number, the first number of an integer, and the first number of ten thousand. Yes, "1" is the first number of tens of thousands, and its status is also the most special. Let's take a look at this magic number with Bian Xiao.

First, the smallest number.

The ancient and huge family of natural numbers consists of all natural numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. 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.

Don't underestimate the smallest "1", which is the unit of natural numbers and the first generation of natural numbers. Humans first recognized "1", and only by using "1" can we get 1, 2,3,4. ...

I told you the special status of "1", which is the first in a thousand miles. Don't underestimate it.
