for myself I learned these techniques and corresponding slang as a kid following gamedev/demoscene tutorials and books like graphics gems, years before my mathematics education caught up. calculus was 3rd year high school (age 17ish) I had been familiar with the concepts from programming for 3 years already. it's a personal style thing but the slang stuck with me and I still use it in adulthood. I'm somewhat pleased that this would cause somebody like you to think somebody like me has poor math literacy ;)
