In mathematics, counting and ranking items are done using natural numbers. This unique set of numbers has been used in daily activities. The alphabet N is used as a symbol to address natural numbers. This set of numbers is represented as N = {1,2,3,4,……….}. They are also known ...
In this chapter, after an introductory section, in Section 1.2 we shall illustrate the axiomatic approach to real numbers, and, in Section 1.3, we shall identify the natural numbers as the smallest inductive subset of . Further information about natural numbers will be discussed in Chapter 3, ...
Informal Definition (Natural numbers)(自然数): A natural number is any element of the set N=def{0,1,2,3,...}, which is the set of all the numbers created by starting with 0 and then counting forward indefinitely. Natural numbers are sometimes also known as whole numbers. We call N ...
In this unit, we shall give a brief, yet more meaningful introduction to the concepts of sets of numbers, the set of real numbers being the most important, and being denoted by R. But first, to get to the real numbers we start at the set of natural numbers. Natural numbers N Natural...

When we first learn to count, we are learning an ordered set of numbers: generally, the so-called natural numbers (1, 2, 3,...). As we gain a deeper understanding of numbers, we add the number 0, forming the whole numbers (0, 1, 2, 3,...).
