For anyone who doesn't know, this is what linear algebra looks like

    y = mx + b

    It's algebra. It's linear. 😬

    No way, dude. Thats affine, not algebra, and not linear. Its a lie meant to divide us.

    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?"

    Thats not too bad. It just takes up a lot of space. Good thing I do my maths on an android tablet
