Find expressions for each of P$\displaystyle \vee$Q, P$\displaystyle \wedge$Q, and P$\displaystyle \rightarrow$Q that use only the

connective $\displaystyle \uparrow$ . (Your answers should not contain the symbol ¬.) In this case the up arrow is a NAND gate.

Not sure how to go about doing this one, any help would be appreciated.
