I agree that math is probably most interesting for Ti and NT types. I never liked math much, I could do well enough to get my MSc. degree in engineering but I never really enjoyed it. It was just too abstract, too removed from the real world and requiring too much memorization and boring pen and paper practice exercises. Any kind of applied math was more interesting, as was geometry. Calculus was the worst I think. Understanding the principles wasn't too hard and instead of practicing how to solve problems I could usually guess in the exam what kind of formula was required for a specific kind of problem and more or less guess my way through. I was content with barely passing grades if it meant that I didn't have to sit and solve math problems, it was just too boring. The ones who actually were excited by math were usually Alpha NTs.
