Math

Last week I purchased a burger for $1.58. The counter girl took my $2 and I was digging for my change when I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and 3 pennies, while looking at the screen on her register.

I sensed her discomfort and tried to tell her to just give me two quarters, but she hailed the manager for help.
While he tried to explain the transaction to her, she stood there and cried.

Why do I tell you this? Please read more about the "history of teaching math":
