You can list all the elements of the set. Or, another way is to use set-builder notation.
For example {x | x < 5} means the set of all real numbers less than 5. You could not list all of these since there are an infinite number.
If you have {x |3 x < 5, x is a natural number } the set of all natural numbers less than 5 and greater than 3, so it is two. You could write this set as {2} or in words say the set that contains the number 2.

What are the two ways of describing set in mathematics with examples?
Roster method and set-builder notation. Example of Roster Method {a, b, c} {1, 2, 3} {2, 4, 6, 8, 10...} Example of Set-builder Notation: {x/x is a real number} {x/x is a letter from the English alphabet} {x/x is a multiple of 2}
Two ways of describing a set?
There are two ways of describing, or specifying the members of, a set. One way is by intensional definition, using a rule or semantic description. See this example: A is the set whose members are the first four positive integers. B is the set of colors of the French flag. The second way is by extension, that is, listing each member of the set. An extensional definition is notated by enclosing the list of members in braces: C = {4, 2, 1, 3} D = {blue, white, red}
