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 ...

To denote negative numbers we add a minus sign before the number. In short, the set formed by the negative integers, the number zero and the positive integers (or natural numbers) is called the set of integers. They are denoted by the symbol $$\mathbb{Z}$$ and can be written as: ...

The set of whole numbers is the set of natural numbers plus zero: {0,1,2,3,…}. The set of integers adds the negative natural numbers to the set of whole numbers: {…,−3,−2,−1,0,1,2,3,…}. The set of rational numbers includes fractions written as {mn|m and n are...
and in which order is preserved by addition. Like the natural numbers the integers form a countably infinite set. The set of all integers is usually denoted in mathematics by a boldface Z (or blackboard bold or Unicode ℤ)which stands for Zahlen (German for "numbers"). ...
