FORMULA + - X =% $

Stupid ... I know math is all abt formula ... But if u now it, u are abt to get a lot of answers even the questions is being phrase in a different wat. I dun even understand y smart ppl like me like to use shortcut and yet the lecture can't just close one eyes and let me go. It even more stupid that wat is on the chart is actually the answers for the next few questions and i had to write the same formula over and over again. Reason is to prove that we know how to do and not copy.

Stupid stupid stupid !!!!!!!!
