Show in at least two different ways that the sets A-(BnC) and(A-B)U(A-C) are equal

Question

myininaya · Answer

Well do you know you can use a truth table to show the equality of those two sets? Or you can just prove the sets are equal by using a non-truth table method...just using the definitions of the sets...which kinda seems similar to me.
