How much do you need to know mathematics for a game developer?

Question

Mathematics

I want to develop games using Unreal Engine (c++) and Unity (c#). Develop both alone and in a team. I appeal to people who already have some experience in developing on these engines. What level of mathematics is needed for free development on these engines?
Games both 2d and 3d.

Answer 1

At least a school geometry course is required. + vector algebra. + trigonometry won't hurt.
For balance - combinatorics.
For graphonia - at least more matrices and transformations over them.
It's so superficial.
For a straight free one, everything near-mathematical that is connected with algorithms, Boolean algebra and logic is still useful. Type there factorials in complexity of algorithms, for example.
