They may be endless (non-terminating) non-repeating decimals.ĭenoted by R, it consists of natural numbers, whole numbers, integers, rational numbers and irrational numbers. It can be easily observed from the above number line that all natural numbers are whole numbers, the set of natural numbers is a subset of the whole numbers, and hence, the set of whole numbers W is the proper superset of the set of natural numbers N. 4 1/3, 8 2/9ĭecimal numbers, Powers and square roots may also form rational numbers.ĭenoted by Q 1, these are numbers that cannot be expressed at fraction (or ratio). A integer is any number that is not either a decimal or a fraction (however, both 2.000 and 2/2 are integers because they can be simplified into non-decimal and non-fractional numbers), this includes negative numbers.
