This.

There's always more you might want to learn, but when people talk about these basics, it's really just being super focused in 4 or so classes, not a whole ivy league undergrad curriculum in math.

probability & stats, multivariable calculus, and linear algebra will take you a long way.

Cool. I will look into those, but I was asking as a general interest in math question. I actually have no interest in machine learning. I'm bored of chasing money. Interested in 3D computer graphics and math for math's sake.

> They haven't needed it, so they haven't retained it even if they learned it in college.

True for me. I knew all of these from my course work when I graduated with my CS degree in 1996. I haven't used them at all in my career, and so I'd be starting basically from scratch re-learning them.
