    Use truth tables to show whether the following two Boolean expressions are equivalent or not

    NOT (A AND NOT B) NOT A OR B

    The way I would do this is to draw several columns: A and B for the first two counting up from 00 to 11 to list all 4 possibilities, then the next two would be NOT A and NOT B, then the next A AND NOT B, the next NOT (A AND NOT B), and the next NOT A OR B. All columns except the first two are easy enough to calculate; if you get stuck then show how far you got and where you got stuck. Comparison of the last two columns will show whether or not the expressions are equivalent.
