I hate it. Always.

One does not need to be good at Mathematics to learn game development. It helps to know some things but you learn it when you need it. The basic things that is used the most is trigonometry and linear algebra with vector and matrix operations.



Linear algebra


Coordinate Systems








  • Scalar variables will use lowercase letters in italics: a, b, x, y.

  • Vector variables of any dimension will use lowercase bold letters. a,b,u,v.

  • Matrix variables will use uppercase letters in bold: A,B,M,R.

  • Angles are given by lowercase Greek letters. α, β, θ, λ.
