- 1Natural NumbersNatural Numbers are normal counting numbers including zero.
- 2Integer NumbersIntegers are positive and negative whole numbers.
- 3Rational NumberQ is the set of numbers that can be written as fractions (ratios of integers).

- 5Real NumbersR is the set of all 'possible real world quantities'.
- 6Ordinal NumbersWhen objects are placed in order, ordinal numbers are used to tell their position. For example, if we have a well-ordered set S = {‘a’, ‘b’, ‘c’, ‘d’}, then ‘a’ is the 1st object, ‘b’ the 2nd, and so on.
