Little monkey went to school, but he was very playful, and his math score was very bad. One day, the giraffe teacher told the little monkey that it was going to take an exam. The little monkey was so anxious that he scratched his ears and gills. He was worried, so he went to the fox for help. The fox said, you can know the answer by flicking your head three times with your finger.
When the exam started, the giraffe asked the little monkey how much one plus one was equal to, the little monkey said it was equal to two, the giraffe said it was right, the giraffe asked the little monkey how much five minus one was equal to, the little monkey said it was equal to four, and the giraffe said it was right. The giraffe asked the little monkey how much six divided by two is. The little monkey couldn't divide. He looked at the giraffe blankly. At this time, the little monkey thought of the fox's words, so he flicked his head three times with his fingers. The giraffe said it was right. The little monkey opened his eyes happily.
The giraffe asked the little monkey how much three times three is. The little monkey couldn't multiply. He blinked. He thought of the fox and flicked his head three times with his fingers. But he still didn't know the answer. The little monkey thought, is it because the play is light? So the little monkey flicked it three times again. But he still didn't know the answer. The little monkey was worried and he flicked his head three times again, There are three bags bulging on its head. The giraffe says it's right. The giraffe laughs at the bulged bag on the monkey's head. The monkey feels the painful skull and blushes（ Fairy tale bar: www.tonghuaba.cn/ Please keep the reprint!)
The giraffe asked the monkey again. As soon as she opened her mouth, the monkey had already run away.
