A real number is a number that can be expressed as a decimal of some form. The integers: -2, -1, 0, 1, 2 The rational numbers: 2 1/2, 3.45, 2/3 The Irrational Numbers: pi, square root of 5, e, 5.8283851920493809... These are all real numbers. Imaginary numbers: i, 5i, 3i + 2, 4i - 3 These are not real numbers.
