 Description  
 Intersection of Sets:  The set of all elements contained in all of the given sets.
The intersection of two sets is formed by putting together the elements that appear in both sets. For example, if  H = {0, 3, 6, 9} and J = {0, 6, 12} then the intersection of H and J is {0, 6} and is written H  J.

If the given sets do not have any elements in common, then the intersection set is an empty set (). In that case, the sets are said to be distinct.
