Wow, that's such a good video. Thanks! Haha, mind blown really. And other than graph theory, I never took a college level math course (I artfully skipped almost all math during my CS degree), I'm doing pre-calculus at the moment, because I want to get better at it.

Very simple and basic.
Edit: incorrectly wrote vectors instead of tensors.
