Work through these gamified tutorials on matrix addition and matrix multiplication. Each of them has a button on the left that says "email scores". Click that button for each of these two, and email it to me (dmusicant@carleton.edu). I don't even quite understand quite what the three scores (total score, percentage correct, health), but send me two emails (one from each assignment) that you're not embarrassed about and you'll get full credit for this quiz.
