One day, a little boy came into a shop. He to the shop assistant(售货员) and said, "I'd like twelve exercise books of six cents each and nine pencils of ten cents each. How much are they?" The shop assistant wrote these down on a piece of paper and thought for a minute. Then she answered, "$1.62."
"If I give you $10, how much money will I get back?"
"You will get $8.38 for change. Here you are. These the things you want."
"No, thanks. In fact, I don't need to buy anything. This is math homework." The boy looked at the piece of paper and asked , "Can I take it away?"
