It is very hard for me to tell the difference between 441.595 and 441.559, even if it is my own handwriting. So I make lot of little errors in the math. What does your system do? Penilize the hell out of me for being disabled. You really need to give people a second chance without any penalty. If they look at the answer, they don't get the second chance. They look at the hint, they don't get the second chance. But if they are able to correct their mistake, DO NOT penalize them. Just don't give them the points. That way the small mistakes and correctables won't keep a person in a stupidly simple exercixe for an hour longer than is needed because of a disability.
