[quote=Anonymous]OP Here - the "need to borrow way" is a little messed up as the numbers ran more together when I submitted than when I was typing them down. The expression on the right side of the original problem is the revised expanded notation once I borrowed "10s" and "100s" so the 600 became 500, 70 became 160 and 2 became 12.[/quote]
