What is a natural number?

All substances in this world are made up of molecules, which is equivalent to numbers. We have all studied natural numbers in primary school mathematics textbooks. In short, a natural number is a number representing the number of objects, including 0, 1, 2 and so on. Is a zero-based infinite loop non-negative integer. Integer contains natural number, so natural number is a part of integer. Because natural numbers represent the number of objects, we can only see integers from zero to infinity, and fractions are invisible to the naked eye. Natural numbers have two characteristics, one is orderly and the other is infinite. Natural numbers also include odd numbers, even numbers, prime numbers and composite numbers. Odd numbers are familiar to us, like 13579. Of course, zero is an even number and a natural number. If you want to study science in the future, it is still very important to learn math well. At first, we should start with these concepts and consolidate the most basic knowledge. Elementary school mathematics doesn't need much computing power. It tests our basic knowledge. Only by remembering these basic knowledge points can we continue to study mathematics in the future. If you are asked who is the smallest natural number, the answer must be zero. Because natural numbers are part of integers and are non-negative, we can also call them non-negative integers. In fact, it boils down to one point. At first, we didn't think zero was the smallest natural number. In 2002, China stipulated zero as the minimum natural number, because France was the first country to use zero as a natural number before. Later, for various reasons, China also revised primary school textbooks to use zero as the minimum natural number. That's what I think of as the concept of natural numbers. I hope everyone can understand that children's study is the most important thing now. Don't be delayed by the internet in the future. You are all pillars of the future motherland. Come on, win glory for our motherland. This is my view on this issue. If you have different opinions, please leave a message in the comments section.
