Question

In digital circuits, all logical gates can be built from only NAND gates.

This is equivalent to saying that all propositional formulas can be built out of NAND operations such as A ∧B. Show, using propositional algebra, how to implement OR with only NAND operations. (Remember that NOT is a gate too, so in your final answer you can only have lines over pairs of ANDed variables, not over individual variables.)
