Hey,
My friend was talking about plotting points on a graph and mentioned quadrants...yeah but i dont remember- if you plot a point directly on the x or y axis doesn't that mean that it's not in a quadrant? Same thing for zero as well no?
I know I'm retarded ( but honestly I just don't remember) and to think that I going into honors PreCalc is a scary thought.

It seems to me that unless an answer is ALREADY known (by whomever has the answer the way THEY DID IT) the order of operations are arbitrary. There certainly are times when the rules make sense, and other times they seem completely whatever some jackass 3000 years ago made up. Switch the order of operations around in an expression (not equation) and you can get all sorts of answers or simplifications. Math is only a perfect language insofar as long as everyone follows the rules! Or am I crazy??
