lol, actually if you have ever seen a matrix (we were only doing 4 x 4 and 5 x 5's) they kind of even look like a game of sudoku. Different principles though . But, matrices are about the only thing in math that I really do not enjoy doing. I do them because I have to, and when (if) I have to teach them then I will do them as well, but other than that I will never do them .
