Math

To develop scientific applications, videogames and other you will need math or even physics. A videogame developer should have knowledge of physics, statistics, algebra or arithmetic and linear algebra. Yes, ofcourse: programming uses math and other traditional disciplines, but leaving out some sectors (videogames, artificial intelligence and embendedd programming) math isn't that important - you won't necessarily need to be good at math, you will just need to have a good logic.

Graphics rendering requires knowledge of some linear algebra, from what I understand. You'll need to know about matrices and matrix operations. As far as calculus goes, I don't think you really need anything much unless you're implementing some sort of physics equation or something. In which case, you can probably learn what you need as you go given that you have an understanding of algebra/trigonometry. The course that has really made a difference with understanding the logic behind computer science was discrete mathematics. You learn about propositional logic, inductive/inductive proofs, set theory, function/relations, algorithms, etc... Really is a great class that ties everything together for you as a student.

I do not agree with you.

Sure, there are some schools of programming that implement a lot of physics, math and algebra, but if you are just considering it as a hobby, some logic and basic algebra will do. programming is about using logic and syntax to get something done.
