I took an applied matrix algebra course when I was in college, BIG mistake! I needed to take a couple of tylenol before each class. I was a business major and that was a recommended math class, I never did find out exactly who it was that recommended it, probably Professor Saruman.
I received an "A", but that was due more to the grace of the teaching professor than to my learning ability, she missed about half of the classes due to a death in her family, so I think she felt sorry for all of us. If we showed up to class and turned our homework in, we did well.
One good thing about higher math is the imaginary number. Just make it up as you go along. Or is that not how imaginary numbers work? Nevermind, you better not take that last bit of advice, for your parents' sakes.
