Combined Operations on Sets

 
4.3 Combined Operations on Sets 
 
  Definition   
     
  Combine operations involve both intersection sets \(( \cap )\) and union of sets \(( \cup )\) at the same time.   
     
  • Combined operations of sets are solved from left to right. 
 
  • However if there are operations in brackets, the operations in brackets must be carried out first
