Oh, I totally get this! That jump from calculus to linear algebra can be such a shock to the system. It really does feel like the rules change overnight, and all those abstract definitions can be super intimidating.

Yeah, it's so true that professors sometimes just drop you into the deep end with these abstract ideas without much scaffolding. I'm really hoping this explanation breaks it down in a way that makes sense, because it's a concept that always tripped me up a bit.

Okay, so the core idea is that a vector space is basically a set where you can add vectors and scale them, and importantly, the result always stays within that set. That closure property seems like the real key to understanding it.
