In this podcast we will cover 2 different number systems; real numbers and non-real numbers.

In this podcast we will cover:

  • Real numbers
  • Non-real numbers


  • Natural numbers: 1, 2, 3, etc., are the numbers you might count with and do not include 0.

  • Whole numbers: The numbers {0, 1, 2, 3, ...} etc. There is no fractional or decimal part.

  • Integers: Negative numbers; -2, -1,

  • Rational numbers: All fractions where the decimal expansion terminates after a finite number of digits, or repeats the same finite number of digits over and over forever.

  • Irrational numbers: Those that cannot be written as a fraction.

  • Non-real numbers: Any negative number with an even root. These numbers are called non-real because they do not have real roots.
