    \begin{array}{l}<br />
 A\backslash B' = A \cap B \\ <br />
 A'\backslash B = A' \cap B' \\ <br />
 \end{array}<br />

    Can you use these?

    How does A minus Complement of B = A Intersection B?

    I can't see it in my mind how that works.

    Set-minus works this way: K\backslash L = K \cap L'.

    So K\backslash L' = K \cap \left( {L'} \right)^\prime   = K \cap L.
