Since you already have plenty of exercises related to linear algebra in your homework, today's quiz is to simply post a question or comment on the course slides.
Two-word comments like, "Cool man!" will not receive any credit. Also remember to write legibly! ;-)
To keep you coming to class (and to make grading easier...), please print out the slide AFTER you have posted your comment, and hand it in before the next lecture.
Please make sure to put your Andrew ID (and not just your name) on the printout, so that we know who to give credit to!
