\begin{definition}[Definition:Logical NAND/Boolean Interpretation]
Let $\mathbf A$ and $\mathbf B$ be propositional formulas.
Let $\uparrow$ denote the logical NAND operator.
The truth value of $\mathbf A \uparrow \mathbf B$ under a boolean interpretation $v$ is given by:
:$\map v {\mathbf A \uparrow \mathbf B} = \begin {cases}
\T & : \map v {\mathbf A} = \F \text { or } \map v {\mathbf B} = \F \\
\F & : \text {otherwise}
\end{cases}$
