While looking at thescreen on her register, I sensed her discomfort andtried to tell her to just give me two quarters, butshe hailed the manager for help. While he tried toexplain the transaction to her, she stood there and cried.Why do I tell you this?Because of the evolution in teaching math since the1950s:Teaching Math In 1950A logger sells a truckload of lumber for $100.
