Product Description
equal if they have exactly the same . This example illustrates that union of sets A and its subset B is the set A.

For example:

The symbol used for the intersection of two sets is '∩'. Therefore, symbolically, we write intersection of the two sets A and B is A  B which means A intersection B.

Union and Intersection
We just saw how to join two sets using "Union" (and the symbol  ). There is also "Intersection" which means "has to be in both". Think "where do they overlap?". The Intersection symbol is an upside down "U" like this:  

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets. The union is written as AB or  A or B . The intersection of two sets is a new set that contains all of the elements that are in both sets. The intersection is written as AB or A and B .
