hi mantastrike

I've made a diagram below.  At the moment I cannot find a neat way to shade bits so I've labelled the 7 regions.  Hopefully you will be able to make a copy on paper and shade the bits as indicated here.

A - B = regions d and g
C - B = regions g and k

So these intersect at g.

A intersect C = regions g and i

(A intersect C) - B = g.

Hence these are the same.
