The Real Number System. All the numbers mentioned in this lesson belong to the set of Real numbers. The set of real numbers is denoted by the symbol [latex]\mathbb{R}[/latex]. There are five subsets within the set of real numbers. Let’s go over each one of them.
The real number system (which we will often call simply the reals) is first of all a set \(\{a, b, c, \cdots \}\) on which the operations of addition and multiplication are defined so that every pair of real numbers has a unique sum and product, both real numbers, with the following properties.

The real number system is a fundamental mathematical construct encompassing the set of all possible numbers, rational and irrational, and serves as the foundation for mathematical analysis. Real numbers are characterized by their ability to represent quantities on a continuous number line, where each point corresponds to a unique real number. The r...
The real number systempossesses several key properties that define its nature and make it a fundamental mathematical construct. Let’s delve into these properties in detail:
The real number system finds applications in various fields and disciplines as a fundamental mathematical construct. Here are some examples of how the real number system is applied in different fields:
Example 1
Simplify the expression:√(9 + √16)
Solution
We start by simplifying the expression inside the square root: = √(9 + √16) = √(9 + 4) = √13 The simplified expression is √13.
Example 2
Solve the equation: |2x – 3| = 7 Figure-2.
1 The real number system. 1.1 What are the reals? moment this is too hard a question! We can give various answers, but for the moment we prefer just to agree a set of axioms— statements we will. assume are true about real numbers. We will base all our arguments on these axioms and on nothing else, and develop all the mathematics we’ve lea.

In mathematics, a real number is a number that can be used to measure a continuous one- dimensional quantity such as a distance, duration or temperature. Here, continuous means that pairs of values can have arbitrarily small differences. [a] Every real number can be almost uniquely represented by an infinite decimal expansion. [b][1]
