HMM. My add math.. fried. My brain just short-circuit and all the formulae were gone. All the trig steps disappeared. All the linear law disappeared. The A also disappeared. I think I'll get a C. But I'm pretty confident for BK now. Hah. I'll prove to you, mister. It's CCL and LCTan's subject on Thursday. They're splendid teachers, I'm the poor student. But I don't want to disappoint them. :) I'm off.
