                Welcome to the Math Quiz!

        You'll start with three lives. 
        Each round, you'll be asked to solve a math problem. 
        If you solve the problem correctly, you won't lose any lives.
        If you can't solve the problem, your lose a life.

        You can gain lives if you solve a problem correctly
        and your lives and level number have the same parity.
        Otherwise, your lives stay the same, even if you 
        solve the problem correctly.

        You can play until you're out of lives.
