Natural Numbers are the set N - 1, 2, 3, 4, ... Whole numbers just add 0 to the natural numbers. Integers are the set of natural numbers, their opposites and zero. Rational numbers may be written as a fraction or as a terminating or repeating decimal. Irrational numbers have non-terminating, non-repeating decimal representations. All of the numbers in the list are real numbers.' Note: The bar over the 6 in -0.6 indicates that the 6 repeats indefinitely
