# Thread: A-B' and A'-B Venn Diagrams?

1. ## A-B' and A'-B Venn Diagrams?

What do these look like?

2. $\begin{array}{l}
A\backslash B' = A \cap B \\
A'\backslash B = A' \cap B' \\
\end{array}
$

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.

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

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

5. hey thanks a lot, now i get it.
