Re: Column AdditionThats a great way of teaching how to carry... doesnt go too quickly either. In my school we could put it either at the top or at the bottom, as long as it was in line with the correct column  so it was clear what the number meant. #5 20070524 23:29:44
Re: Column AdditionThanks, people! "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #6 20070525 23:44:34
Re: Column AdditionNo. Well yes. I just wanted to ask you, do you trust me, puppet? (kidding) I see clearly now, the universe have the black dots, Thus I am on my way of inventing this remedy...
