This question is kind of vague.
Many of your everyday situations use the rational numbers (fractions and integers), which are a subset of real numbers.
If you do anything with angles (like surveying, or navigation) then irrational (which are still real) come into play.
There are situations when it's necessary to consider complex (a combination of real and imaginary) numbers. When dealing with waves or periodic motion, imaginary numbers become an important thing to consider.
What else can I help you with?
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.
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.
Are -1 and 1 real numbers?
Yes, -1 and 1 are real numbers. Real numbers consist of irrational numbers, rational numbers and integers.
Are real numbers irrational numbers?
No, but the majority of real numbers are irrational. The set of real numbers is made up from the disjoint subsets of rational numbers and irrational numbers.
True or false irrational numbers are not real numbers?
False. Irrational numbers are real numbers.
