Undefined!

As I've mentioned before, I am taking Linear Algebra to get ready for starting a doctoral program in the fall (fingers crossed, applications in). Despite being an accountant, higher level math doesn't come naturally and I feel like I will probably need a 16 year-old kid to tutor me in this class. My professor is a neat guy, who's clearly enthusiastic about the subject and that helps the time fly by. Today he said perhaps the funniest math quote I've ever heard and I thought I'd share it with you. Until today, I had always heard that dividing by zero provided an "undefined result," whatever that means. Today my math teacher really cleared things up for me. He said, "We know if we divide by zero, it makes God cry." That seems just as likely to me as this mythical "undefined" and I don't plan to divide by zero any time soon! I hope that's on the next test, I won't forget it anytime soon.
