The real number system is a mathematical field.
To start with, the Real number system is a Group. This means that it is a set of elements (numbers) with a binary operation (addition) that combines any two elements in the set to form a third element which is also in the set. The Group satisfies four axioms: closure, associativity, identity and invertibility.
In addition, it is a Ring. A ring is an Abelian group (that is, addition is commutative) and it has a second binary operation (multiplication) that is defined on its elements. This second operation is distributive over the first.
And finally, a Field is a Ring over which division - by non-zero numbers - is defined.
There are several mathematical terms above which have been left undefined to keep the answer to a manageable size. All these algebraic structures are more than a term's worth of studying. You can find out more about them using Wikipedia but be sure to select the hit that has "mathematical" in it!

What are the characteristics of a complex number?
A complex number must have a real and imaginary part. It can be in the form: a + bi i is an imaginary number and a and b are real numbers
Are natural numbers real numbers?
Yes, all natural numbers are real numbers. Natural numbers are a subset of real numbers, so not all real numbers are natural numbers.
What rational numbers are real numbers?
All rational numbers are real numbers.
What is the relation of complex numbers to real numbers?
Complex numbers are a proper superset of real numbers. That is to say, real numbers are a proper subset of complex numbers.
What are the component of real numbers?
Real Numbers cannot be the square root of a negative number. Real Numbers are not divided by zero. Basically, Real Numbers cannot be anything that is undefined.
What are characteristics of square root functions?
There are two square root functions from the non-negative real numbers to either the non-negative real numbers (Quadrant I) or to the non-positive real numbers (Quadrant IV). The two functions are symmetrical about the horizontal axis.
What are the characteristics of a complex number?
A complex number must have a real and imaginary part. It can be in the form: a + bi i is an imaginary number and a and b are real numbers
Can a number be a member of a set of real numbers and the set of irrational numbers?
Sure. Those characteristics address different features of a number.Sqrt(2), sqrt(3), sqrt(5), " e ", and " pi ", are all real and irrational numbers.
What is the real characteristics of stingrays?
The real characteristics of stingrays is that it has eyes on top of its head.
Are natural numbers real numbers?
Yes, all natural numbers are real numbers. Natural numbers are a subset of real numbers, so not all real numbers are natural numbers.
Are all numbers real numbers?
No, not all numbers are real numbers. Real numbers include all rational and irrational numbers, but there are also complex numbers that are not considered real numbers.
What numbers are not real?
Imaginary numbers are not real numbers.
What rational numbers are real numbers?
All rational numbers are real numbers.
Is a real number a whole number?
No, not all. All numbers are Real Numbers. * * * * * All numbers are not real numbers: there are complex numbers and others. Also, all real number are not whole numbers. sqrt(2) or pi, for example are real numbers but not whole numbers.
What is the set of numbers including all irrational and rational numbers?
real numbers
What is the relation of complex numbers to real numbers?
Complex numbers are a proper superset of real numbers. That is to say, real numbers are a proper subset of complex numbers.
Are real numbers natural numbers?
No. Natural numbers are a proper subset of real numbers.
