I do not approve of posting some messy-ass scanned copy of handwritten arithmetic in the homework forum. To me this "cheapens" the forum and gives it the appearance of being "second-rate". I can tolerate one or two but it's starting to get more than that. I say if you got more than 100 post, there is no excuse for not learning a couple of basic LaTex commands. However I don't wish to go over the mentors head and directly criticize them in the HW forum.
