What is the meaning of real numbers in math?

In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line (or alternatively, a quantity that can be represented as an infinite decimal expansion).

What is the definition of real numbers with examples?

A real number is any positive or negative number. This includes all integers and all rational and irrational numbers. For example, a program may limit all real numbers to a fixed number of decimal places.

Is 3.14 a real number?

The number 3.14 is a rational number. A rational number is a number that can be written as a fraction, a / b, where a and b are integers.

How do you identify real numbers?

The Real Number Line is like a geometric line. A point is chosen on the line to be the “origin”. Points to the right are positive, and points to the left are negative. Any point on the line is a Real Number:

  1. The numbers could be whole (like 7)
  2. or rational (like 20/9)
  3. or irrational (like π)

What are not real numbers?

Imaginary numbers are numbers that cannot be quantified, like the square root of -1. The number, denoted as i, can be used for equations and formulas, but is not a real number that can be used in basic arithmetic. You cannot add or subject imaginary numbers. Another example of an imaginary number is infinity.
