I can seem to do most of them however when the expression is a little long i just seem to make it longer and more confusing rather than simplifying it.

Q1) $\displaystyle (A - B^c) \cup (B \cap (A \cap B)^c) $

Q2) $\displaystyle [(A \cap B)^c \cap A] \cap B^c $

Can someone please explain how to simplyfy these =/

And sorry dont really know the syntax for all the maths (the c is meant to be compliment).

thanks
