Roster method of Sets- tabular method of Sets

For the three sets namely the set A of all odd numbers less than 10, the set B of all states of South India  and the set C of all  even natural numbers less than  or equal to 10, list out all their elements.

The list of elements of A are 1, 3, 5, 7, 9.

The list of elements of B are Karnatka, Andra Pradesh, Tamilnadu and Kerala.

The list of elements of C are 2, 4, 6, 8, 10.

We use thefollwing notation to represent this A = {1, 3, 5, 7, 9}; B = {Karnatka, Andra Pradesh, Tamilnadu and Kerala} and C = {2, 4, 6, 8, 10}. This method of representing a   set by  writing all its elements is called Roster method or  Tabular method. So, Roster method or Tabular method is a method  in which we write all the elements inside a pair of brackets {}.
