1. Roster Method -listing the elements in any order and enclosing them with braces. Example: A= {January, February, March…December} B={1,3,5…}
2. Rule Method -giving a descriptive phrase that will clearly identify the elements of the set. Example: C={days of the week} D={odd numbers}
3. Set builder notation i.e B = {x | 1 < x < 10 and 3 | x}
4 cardinal number of a set in a curly bracket {…}. ... Statement Form: Example-A = {Set of Odd numbers less than 9}
5 Subsets-Above, we defined two sets A and B to be equal if every element of A is an element of B, and vice versa. If we remove the “vice versa” from this definition, we get the definition of a subset.For example, consider the sets C = {1, 2} and D = {1, 2, 3, 4}. The set C is a subset of D, because every element of C is also an element of D. So we can write C ⊆ D. A given set has many subsets; for example, another subset of D is {1, 3, 4}.
