Linear Algebra is so cool

Funny thing is, it really should be more accessible since in the higher levels of Calculus, professors assume knowledge of determinate, and I had never seen a matrix before that point in my curriculum. Reminded me of 2 dimensional arrays from programming though. It really held me back in trying to understand the materials of that course. Although, if I remember right, it might have been possible that we just ran out of time in high school math (algebra or calculus), and never covered it. Still pisses me off when you supposedly take the highest level of something in high school that transfers over to where you are placed in college, and even when the facilities are not 15 miles from each other, they can't coordinate the material expected to be known by the students. It gives off a real rude atmosphere when you lack assumed knowledge after fulfilling all the requirements to be in the course. I actually dropped a history course because the professor was being a real prick about it.
