I'm kind of confused that it is romanized as "Ten'i", when in the anime it sounds more like "Tein!". Though the kanji should be correct, as I got them from the raw.

For Maths, it was derrivatives and cubic equations (one of the derrivatives resulted in a cubic equation, though I assume that it was meant to be solved differently).
