Natural numbers are those who from the beginning of time have been used to count. These decimal numbers which are neither exact nor recurring decimals are characterized by infinite nonperiodic decimal digits, ie that never end nor have a repeating pattern. Thus, the set is not closed under division. All integers are rational numbers; for example, the number 5 may be written as . Also means rational numbers are repeating or terminating decimals. So it is not an irrational number. To which subset of real numbers does the following number belong? Here are some algebraic equations, and the number set needed to solve them: We can take an existing set symbol and place in the top right corner: And we can always use set-builder notation.
