What are Real Numbers?

Real numbers are the collective set of rational numbers and irrational numbers.

Ration numbers are an expression of two integers as a ratio. They include:

  • Natural numbers -- the numbers we count with
  • Whole numbers -- the natural numbers including zero
  • Integers -- whole numbers including negative versions of natural numbers
Irrational numbers are numbers that cannot be expressed as a ratio of two integers.
