$\displaystyle \begin{array}{l}

A\backslash B' = A \cap B \\

A'\backslash B = A' \cap B' \\

\end{array}

$

Can you use these? - Oct 10th 2007, 02:42 PMEdbaseball17

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

So $\displaystyle K\backslash L' = K \cap \left( {L'} \right)^\prime = K \cap L$. - Oct 10th 2007, 03:13 PMEdbaseball17
