The natural number is 0, 1, 2, 3, ............................................................................................................................................................

A prime number can only be decomposed into the product of 1 and itself, such as 2=2* 1, 3=3* 1, 5 = 5 * 1 ...

The complex number is simply I, and i= root number-1. The general expression of complex number is a+bi, I don't know if I remember correctly.

Rational numbers mean that both integers and fractions are called rational numbers (circular decimals can be divided into numbers, and call me if you are interested in concretization).

Irrational number is a number in real number that cannot be accurately expressed as the ratio of two integers, that is, infinite acyclic decimal. Such as pi, the square root of 2, etc.

Real number is a general term for rational number and irrational number.

Here is a classification or grading. The complex number is the largest, and the complex number is divided into real number and imaginary number (that is, the root sign-1). Real numbers are divided into rational numbers and irrational numbers. Rational numbers include integers, fractions and decimals. Integers are divided into positive integers and negative integers. Positive integers used to be divided into natural numbers and 0, and now 0 is also reduced to natural numbers.

I don't know if I'm satisfied. It's been useless for a long time. I almost forgot. You can go to Baidu to search for the explanations of these names respectively.
