A real number is any positive or negative number available within the entire mathematical range of numbers. Real numbers include whole numbers, rational numbers, irrational numbers and virtually any type of number that is not an imaginary number or that can’t be computed or processed logically. ...
What is a real number?Imaginary Numbers:Imaginary numbers are also called complex numbers. When imaginary numbers are squared, the result is a negative number. Imaginary numbers are used in certain calculations, such as quadratic equations. They are the result of a real number multiplied by i, ...
What is a real number and what are examples of real numbers? Kinds of Numbers: Sometimes mathematics can seem confusing because there are many different kinds of numbers with differing properties. There are real numbers, imaginary numbers, rational and irrational numbers, prime numbers, whole n...

A real number is any positive or negative number. This includes all integers and all rational and irrational numbers. Rational numbers may be expressed as a fraction (such as 7/8) and irrational numbers may be expressed by an infinite decimal representation (3.1415926535...). Real numbers that...
What are Real Numbers in Math? Real numbers include rational numbers like positive and negative integers, fractions, and irrational numbers. In other words, any number that we can think of, except complex numbers, is a real number. For example, 3, 0, 1.5, 3/2, √5, and so on are re...
But what is a real number ? This chapter precisely answers this question and relates the answer back to our study of symmetry. It ends with an optional "Elements of Mathematics" section that uses equivalence relations to define rational numbers and real numbers even more rigorously....
What is a rational number between 2.8 and 2.9? What can a rational number be written as? What are some rational numbers that are not integers? What is a positive rational number? What is a real number that is not rational? Which of these numbers is not rational? A.) 3^2 B.) .25...
What are the "real numbers," really?The short, simple answer used in calculus courses is that a real number is a point on the number line. That's not the whole truth, but it is adequate for the needs of freshman calculus. The freshman calculus course (at most universities nowadays) ...
Real numbers are basically all the numbers you could think of if somebody told you to think of a number. HowStuffWorks Math is pretty confusing — at least to people who don't understand it. Which is a lot of us. The thing about math is you have to learn terms to understand what nu...
