Sungbum did his calculation on the back of the award he got yesterday. I was surprised by his intrepidity ( the reason why it was such a daring thing to do was that Chad'd probably get mad once he sees the ugly caculation scribbled behind the award). Well, it is unlikely that Chad would check Sungbum's award just to see if Sungbum's done something bad on it; plus he may not even care about it if not appreciate it. Who knows* if he buys the arithmatic beauty of calculations.
