Thanks, everyone. We're looking for a new printer/scanner, so I'm glad I asked this question before purchasing.

I've had another look at the math teacher's last email and it seems to be the word problems, specifically, for which an alternative process is sought. DS7 is still painfully slow at typing. Typing on worksheets will be our way forward once we get his speed up, but right now it would try the patience of a saint to supervise that kind of homework.

Oddly, I think I'm asking for word problem sites that don't involve words! At least not words typed by the user. Does ALEKS fit that strange description?
