I always hear that Ti types are good with math. Math is full of frameworks and principles, and some geniuses can use them to solve complex arithmetic in their heads in seconds.
Still, I wonder about whether the actual handling of numbers is Te. You may have good frameworks or principles with numbers, but does this help with complex algebraic formulas such quadratic equations, calculus, etc. Since that aspect of math is basically arranging external things (the visible figures before you), it seems more Te'ish. I guess having certain principles internally might help, but do any Ti types find difficulty with shuffling around the numbers and variables, and are Te types better at that stuff, and thus can just do the problem set before them, and not even need to internalize principles?
