Who's the idiot who said this was Calculus?
It's fucking algebra...
Once you get into AP Calculus or upper level math, stuff flies over most peoples heads. It gets into shit with theories and proving stuff with theories but you never do any actual math.
It's like "If this happens, and this happens at this point, this might happen because this theory says it might." "Zomg A+!!!"
It's bullshit shenanigans, I just stopped going to that class... literally had 60+ absences in a 90 day semester... that and I decided mah career wouldn't require any upper level math so I just said fuck it....
