Using the 'return' keyword will return whatever follows it (nothing, in
this case). However, it also stops your function from doing anything else.
Think of it as telling the function "stop here, and do nothing else. Just
quit now."

This line will never execute, because you've already returned.

You now return a number, not nothing as before, but the result for your
function is the same. Your print statements must be *before* the return
statements.
