Sorry doctor woodpecker.

(Mathematical Fairy Tales)

In a dense forest, an old pine tree was ill, and Dr. Woodpecker came to treat him. Grandpa pine said, "Dr. Woodpecker, come and save me." I was enchanted by a witch, and my body was covered with arithmetic problems. As long as the calculation is correct, it can help me find the bug. If you miscalculate, my skin will harden and your mouth will not open, and the worm will kill me. "

Dr Woodpecker listened to Grandpa Pine's words and carefully looked at the arithmetic problem above:

67+8=( ) 28+30=( ) 3+42=( )

…… 52-8=( ) 76-20=( )

Dr. Woodpecker said, "It's too simple. I'll fill it in for you now. "

Grandpa Pine smiled and said, "Thank you, Dr Woodpecker. Please do it with your heart. I will always wait for you! " "

After a while, the woodpecker said, "Grandpa Pine, I did it all. Are you comfortable now? "

67+8=(85) 28+30=(58 ) 3+42=(45 )

…… 52-8=(44) 76-20=(46)

Grandpa Pine said, "It's much more comfortable than before, but it's still a little uncomfortable!" Please check it again! "

The woodpecker smiled and said, "I am very serious about this problem." Just do it once. Diseases come on horseback, but go away on foot. You will get better gradually. I must treat other big trees. I have to go first. Goodbye! " Grandpa Pine also happily waved goodbye to the confident woodpecker doctor.

I don't know how many days later, when Dr. Woodpecker passed by the forest where Grandpa Pine lived again, she found that Grandpa Pine had no leaves, bare and withered trunk. How did Grandpa Pine die? Didn't I cure him of his illness? Did I miscalculate? ...

Listen, "Woohoo ……" is the cry of Dr. Woodpecker. Grandpa Pine died, and now she really regrets it! Clever boy, did you find Dr. Woodpecker's mistake? We don't want to learn from her. Remember to check more when you finish the questions!

Mom's comment: There is an interesting topic on the children's math homework today. It's a picture of a big tree with several arithmetic problems on it for woodpeckers to judge right or wrong. The children have made up a fairy tale based on this topic, and welcome your valuable suggestions!
