Sally was fourteen. She studied in a middle school. She liked dancing and singing and spent a lot of
time on them. But she hated math and even decided to give it up. Her father was anxious about it.
It was Sunday. Sally's father gave a call to his sister who taught math in another school. He hoped she
would come and tell his daughter how to learn math. The woman came and said, "You are a clever girl,
Sally. I'm sure you will soon learn math well if you do your best. "
"I'm afraid I can't. Aunt," said Sally, "Girls can't be good at math. "
"I don't think so," said the woman. "I was good at it when I was a girl. You must do more exercises and
try different ways to practice doing math problems until you work them out or at least understand them
better. Here is a math problem. Please think it over and see if you can work it out. "
"OK," said the girl, "Let me try. "
About an hour later, Sally took the. exercise book to her aunt and said, "I've tried several times and
worked out the problem at last. "
"Well done!" her aunt looked at her answer and said happily, "Now you see, math is not as difficult as
you thought. "
