If y'all are wondering why I'm in a constant state of "freak out"...

If y'all are wondering why I'm in a constant state of "freak out" this is what Linear Algebra looks like. Between this and Discrete CS I am definitely learning a new language with all these symbols. I don't see the mirrored "E" on this sheet, but there are some of the upside - down letters "A" near the top. It's crazy how so much of the material in my classes is related. I guess I'm learning where mathematics and computer science converge. It's all super interesting. But NOT easy.
