The ∪ means union so A ∪ B mean all of A and all of B
∩ Means intersection so A ∩ B would mean the area that is A and B overlap on
' means complement, with is everything that is not A. I this case A' would be everything that is not in the A circle

Bleh formatting messed up
' means complement which is everything that is not itself. In this case, A' would be everything that is not in the A circle
