Equivalent expressions are "x is a member of A", "x belongs to A", "x is in A" and "x lies in A". The expressions "A includes x" and "A contains x" are also used to mean set membership, however some authors use them to mean instead "x is a subset of A".

A number that can be made as a fraction of two integers (an integer itself has no fractional part). In other words a/b is a rational number when a and b are numbers like -2 or 7 or 123. But be careful: b cannot be zero. There are numbers that cannot be written like that, such as π (pi), which is an "Irrational Number".

Q: Set of all rational numbers; R: Set of all real numbers; Z +: Set of all positive integers; Order of Sets. The order of a set defines the number of elements a set is having.
