Made using Desmos. Amy Feraco. Real Number Properties The following sets of numbers are all part of the real number system : Natural numbers N : Positive whole numbers. Whole Numbers W : Natural numbers and zero.
Integers Z : All whole numbers and negative numbers that are not decimals. Rational Numbers Q : Fractions, integers, decimals that end, and repeating decimals. Real Number Properties and Operations Real numbers have some really cool properties, like the reflexive , symmetric , and transitive properties. Also: The sum of two real numbers is always a real number. The difference of two real numbers is always a real number. The product of two real numbers is always a real number. The quotient of two real numbers is always a real number.

Natural numbers are used for counting objects, rational numbers are used for representing fractions, irrational numbers are used for calculating the square root of a number, integers for measuring temperature, and so on.
These different types of numbers make a collection of real numbers. In this lesson, we will learn all about real numbers and their important properties. Any number that we can think of, except complex numbers , is a real number.
Real numbers include rational numbers like positive and negative integers, fractions, and irrational numbers. This indicates that real numbers include natural numbers, whole numbers, integers, rational numbers, and irrational numbers. For example, 3, 0, 1. Now, which numbers are not real numbers? These numbers include the set of complex numbers, C. Observe the following table to understand this better. The table shows the sets of numbers that come under real numbers. We know that real numbers include rational numbers and irrational numbers.
Thus, there does not exist any real number that is neither rational nor irrational. It simply means that if we pick up any number from R, it is either rational or irrational. The numerator in the fraction is represented as 'p' and the denominator as 'q', where 'q' is not equal to zero.
A rational number can be a natural number, a whole number, a decimal, or an integer. In this case, the decimal value never ends at any point. Real numbers are represented by the symbol R. Here is a list of the symbols of the other types of numbers. All numbers except complex numbers are real numbers.
Therefore, real numbers have the following five subsets:.
