      One time at work I was trying to work out a least-squares fit using linear algebra.

      I have no background knowledge in linesr algebra, it felt like drawing a pentagram on the floor and chanting in backwards Latin.

      That’s not a fair example, I know what linear algebra is but can’t tell what’s going on.

      Change of basis would be my guess, but that’s pretty basic.

      You could’ve provided something far worse, like a manual construction of the Jordan normal form of a large matrix.

        It’s been more than a handful of years since I had to learn linear algebra so I am very out of practice, and this was the first image that I saw that made me go, “yeah, that looks about right.” I thought I should include some image since I have told people during college that I was in a linear algebra class and several had the same response of, “Really? I learned algebra in high school. Weren’t you in calculas last semester?”
