The method generally known as set notation involves the curly brackets {} with terms separated by commas inside. A set would be A = {1, 2, 3, 4, 5}.
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: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 denoted by enclosing the list of members in curly brackets:C = {4, 2, 1, 3}D = {blue, white, red}.
a.Roster Method:By listing ex:A={1,3,5,7} b.Rule Method:By describing/defining ex:A={the first odd numbers}

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}
