In math we use letters of different types variables for the notation of different quantities. The letters contain capitalized letters as well as lower case for notation. The variables/symbols are used primarily for variables and some fixed quantities used in mathematics. Let’s use some symbols: is any number that we can find in the real world.

We have numbers all around us. Natural numbers are used to maintain count of objects, Rational numbers are used to denote fractions, Irrational numbers are used to derive the square root of any number, Integers are used to maintain the temperature, etc. A set of real numbers is a group of numbers of the different kinds: real, integer, rational, irrational, algebraic, etc. Set is a collection of objects.
Characterizing properties
Real numbers are fully defined by their basic properties which may be summarized by saying that they are an ordered field that is Dedekind complete. “Completely characterized” is intended to mean that for any two such Dedekind complete ordered fields there is a unique isomorphism between them, and hence that the elements of the two fields have exactly the same properties. This means one can work with real numbers and calculate on them knowing.
What does R mean in math?
In mathematics, we like to use different kinds of letters/ variables to denote different quantities. The letters are both uppercase and lowercase letters for notation. In mathematics, the symbol R normally denotes the real numbers.
So when we see “R” in mathematics, often what we’re talking about is this whole field of numbers that encompasses integers, fractions, decimals, numbers that are irrational, for example, pi, numbers such as the square root of 2.
Complete step by step solution
We know that all the numbers in the universe are complex numbers. The complex numbers are further divided into Real numbers and Imaginary numbers. We can label the big world of all the real numbers with the big R that does not need to be written out. In maths, the letter R is usually used to represent the set of all real numbers.
What are Real Numbers?
All of the numbers that we can conceive of, except complex numbers, are real numbers. Real numbers are a very basic concept in mathematics which includes rational and irrational numbers.
They can be represented on a number line and include all the numbers we normally use in everyday calculations and measurements.
Types of Real Numbers?
Natural Numbers (ℕ)
Counting by 1s, 2s, 3s, 4s, etc.
Example: 1, 2, 10
Whole Numbers
All natural numbers inclusive of 0.
Example: 0, 3, 8
Integers (ℤ)
Contains all integers and their negative values.
Example: -5, 0, 7
Rational Numbers (ℚ)
numbers that can be expressed as a fraction of two whole numbers (p/q where q is not zero). Includes repeating and terminating decimals.
Example: 1/2, 3, 0.75
Irrational Numbers
cannot be written as fractions; the decimal form is non-terminating and non-repeating.
Example: √2, π, e
Real Numbers (ℝ)
Contains all of the above, rational and irrational numbers.
Example: -3, 0.5, √3
Conclusion
In mathematics, the letter R is most commonly used to denote the set of real numbers. So, when you see the letter “R” used in math, it’s generally referring to this whole big set of numbers that we have – the integers, the fractions, the decimals, and the numbers that are irrational so they can’t be written exactly, like pi and the square root of 2.

Reals are a basic mathematical concept that include rational and irrational numbers. They can be illustrated on a number line and comprise the full range of numbers which we normally use in our day-to-day calculations and measurements.
