The difference of the sets A and B in this order is the set of elements which belong to A but not to B.

- wherein

Symbolically, we write A – B and read as “A minus B”.

 

 (A-B) U (B-A)= (AUB)-(A\capB)

\left ( A\cup B \right )-B

Option 2)

A-\left ( A\cap B \right )

Option 3)

\left ( A-B \right )\cup \left ( B-A \right )
