Scene 1

Poor Harry pleaded desperately: "Sir, please, I still don't get it!"

His math teacher sighted: "Well, well, well. A fraction is a way to write numbers. Take 1/4, for instance. The denominator 4 represents how many pieces a number is divided into, and the numerator 1 represent how many pieces there are."

Harry stared thoughtfully for a while: " But, sir, I still don't get it." He said innocently.

The math teacher had had enough: " Potter, how many stupid pills did you take today?"

Harry is really confused now: " is that a question?"

"No. I just wanted to test if you can count."
