Vectors, what even are they? | Essence of linear algebra, chapter 1

I imagine many viewers are already familiar with vectors in some context, so this video is intended both as a quick review of vector terminology, as well as a chance to make sure we're all on the same page about how specifically to think about vectors in the context of linear algebra.

Kicking off the linear algebra lessons, let's make sure we're all on the same page about how specifically to think about vectors in this context.

Typo correction: At 6:52, the screen shows
[x1, y1] + [x2, y2] = [x1+y1, x2+y2].
Of course, this should actually be
[x1, y1] + [x2, y2] = [x1+x2, y1+y2].
