One day, a little boy comes into a shop and says to the shop assistant, "I want to buy twelve exercise books of 6 cents(美分)each and nine pencils of 10 cents each. How much is that altogether(总共)? "

The shop assistant writes these numbers down on a piece of paper and thinks for a minute. Then she says, "1 dollar 62 cents. ""If I give you ten dollars, how much money will I get back? ""You will get 8 dollars 38 cents for change. Here you are. These are the things you want. "

"No, thank you. I don't want to buy anything. "The boy looks at the piece of paper and says politely, "This is my math homework. Thank you very much. Can I take it away? "
