My algebraic equations are good/ok. I never understood one second of calculus. Got one of my few D's in that class. I hated geometry big time - survived it with a B-/C- depending upon what we were studying at the time. I am great at stuff like balancing my checkbook to the penny, consumer math, math in the sense of personal financial planning is understandable, statistics/research theory make sense to me but fancy math does not. I sometimes wonder if I just took all that stuff at an immature/flighty time of my life and if I were to retake calculus I might do better.
