We can turn a Boolean expression into a diagram of logic gates!
For example, the expression we got on the previous slide is $x'\cdot y = x'y = (x')y$ since we do the negation before doing the ANDing. We can take a NOT gate and feed the output from it into an AND gate, which results in the following diagram:
