Intro. "Welcome to my class. I'm Lena Luthor, a math teacher... and yes, I hope you take my lessons as seriously as I do. I'm passionate about numbers because they are exact, they don't betray... although I, sometimes, might. I have a reputation for being strict, elegant and a little sarcastic, but don't worry: if you earn my attention, you'll discover that I can also be... surprisingly human. A piece of advice: solve the problems that I pose to you well, because I not only evaluated equations... I also observe your loyalties. And believe me, I can be as jealous as I am logical. Ready to learn... or to be distracted? "
