At first, Lin Yu's idea was to let Little Mango do the wrong questions again to see if she made any mistakes because of carelessness. If she made mistakes because of carelessness in the exam, she can now correct the wrong questions and prove her knowledge.

is clear.

Lin Yu knew that Little Mango was a very worried child. After this lesson, he would definitely learn from it next time and would not make careless mistakes again. Lin Yu still had great confidence in Little Mango.

When encountering such a question, he can stop talking about it.

So he handed the paper to Xiao Mango and asked her to do the wrong questions again.

After a while, Little Mango handed the completed test paper back to Lin Yu.

The moment he saw the paper, Lin Yu felt like he was not feeling well.

"Mango, are you sure you have solved all the wrong questions?" Lin Yu asked suspiciously.

The little guy nodded vigorously, "I'm done."

Before Lin Yu asked the little guy to do the questions, he used an eraser to erase all the wrong answers that Little Mango had made before, so Little Mango just had to do it again on the blank space.

However, the paper that Lin Yu held again was exactly the same as before it was erased with an eraser. Not a single question had changed.

No, it can’t be said that there haven’t been any changes, there are still some changes, that is, it may not have been so wrong before, but it is even more wrong now.

Lin Yu felt a deep sense of frustration in his heart. It turned out that Little Mango was not careless, but really couldn't do it.

But if you don’t know it, then you won’t know it. As long as you explain it carefully, the little guy is so smart, he will be able to solve all the wrong questions right at once.

Lin Yu started to lecture Little Mango with good wishes.

Facts have proved that as beautiful as the dream is, the reality is so cruel.

"Dad, let me tell you about this question. Mango, look, there are seven birds on the tree. On the other side of the picture, these three birds have flown away. I want you to make a calculation according to the picture. How should you write it? First of all

We have to think first, if the bird flies away, it is reduced. If something is reduced, should we use addition or subtraction?"

Little Mango thought for a while and said, "If it's reduced, use subtraction."

Lin Yu was very happy. It seemed that Little Mango was not incompetent at all, but probably just didn't remember it at once. He continued gently, "By the way, if you want to reduce, use subtraction, so how should the formula for this question be listed?

"

Lin Yu felt that this kind of arithmetic problem within ten was not difficult, and with his guidance, Little Mango would definitely be able to teach it.

For the first time, he overestimated himself and also overestimated Little Mango.

Little Mango thought hard for a moment, "73=10."

Lin Yu was stunned for a moment, but he was not in a hurry, and continued to guide the little mango patiently, "Didn't Mango just say that to reduce is to use subtraction? Then look at whether the little bird has increased or decreased."

Little Mango looked at the picture for a while and said, "It hasn't increased or decreased."

Lin Yu couldn't believe his ears and took a deep breath.

Little Mango just didn't react for a while, so he had to teach her patiently and patiently. Lin Yu often saw videos on the Internet about parents tutoring their children's homework, with all kinds of yelling and anger, and some even having cerebral palsy due to anger.

He feels that these are irrational parents. It is impossible for a truly quality, connotative person who has good control over his emotions to treat his children like that.

And as for children’s tutoring homework, aren’t they all very simple questions? It’s impossible to teach them. If the children really don’t understand anything, it’s because parents have no way to educate their children.

It's the parent's problem, not the child's.

Although Lin Yu was shocked by the answer given by Little Mango, he was not angry because of Little Mango's answer. He firmly believed that an excellent father could teach his children arithmetic problems.

Lin Yu pointed at the picture gently and said, "Mango, take a closer look at these little birds and look at the direction in which they are flying."

Little Mango poked his chin with the back end of the pencil, then stared at the picture without saying a word.

His expression showed that he was thinking very seriously. After a moment, he suddenly said as if he had thought of something, "73=10."

"Isn't that the answer I just mentioned? No, I'm telling you it's wrong. Please look at the picture carefully." Lin Yu tried not to get angry, but his voice was obviously raised.

The little guy continued to look at the pictures with his little eyebrows furrowed.

Lin Yu felt that the guidance might be useless. The little guy's thinking was already stubborn, and continued guidance might not lead to the correct answer.

He decided to change his mind.

"Little Mango, look carefully and see the direction of the bird's flight. This kind of question asks you to make calculations. If the bird flies in the direction of the tree, then it is addition. You can use the number of birds on the tree plus the number of birds flying in.

Number of birds.

But if the birds are flying in the opposite direction of the tree, that means they are flying away. To use subtraction, just subtract the number of birds that flew away from the number of birds in the picture, which is the number of remaining birds."

Lin Yu explained all the ideas for explaining the diagram in one breath, and thought that it was perfect.

He looked at Little Mango with questioning eyes, "Do you understand?"

The little guy hesitated for a moment and whispered, "I understand."

His voice was low and he had no confidence. It looked like he didn't understand. Lin Yu raised his voice and asked again, "Do you really understand? Don't lie."

The little guy shook his head again, "I don't understand."

Lin Yu took a deep breath.

He felt that he had mistakenly overestimated himself and Xiao Mango just now.

"Tell dad what you don't understand." Lin Yu thought it was best to prescribe the right medicine. If the child's misunderstanding can be solved, he will really know this question.

Little Mango glanced around the picture and shook his head.

"Then please list the calculations." Lin Yu asked.

"73=10." Little Mango continued.

Lin Yu couldn't help but raise his voice again, "How many times do you have to tell me, 73=10 is wrong."

"73 is equal to 10." Little Mango argued.

Lin Yu felt like his nose was going to be twisted with anger, "It's not that 7 plus 3 is not equal to 10, but the application of this calculation here is wrong."

The little guy blinked at Lin Yu with a pair of big doubtful eyes.

"This question should be 10-3=7." Lin Yu said the answer directly.

Telling the answer directly did not get the little guy to suddenly realize it, but instead got her eyes looking more confused.

"Why?" Little Mango asked.

Why?

Do you still have to ask why?

Lin Yu asked in his heart.

"The birds flew away. There were originally 10 birds on the branches. Then three flew away. Now there are only 7 birds left on the tree." Lin Yu growled.

"Dad, how do you know these birds are going to fly away?" Little Mango asked seriously.

Lin Yu’s head is full of black question marks???

how could I know?

I can see it.

You can see it in the picture.

Lin Yu swallowed, "Dad saw it in the picture. Look at them flying in this direction, aren't they just flying away?" He pointed to the direction of the birds' flight.

Little Mango shook his head, "Dad, I think you are wrong. These birds don't actually want to fly away. They may just be exercising next to the branches and will fly back later. How can you say they are leaving?"

What? Dad, what you did is wrong, if you lose weight like this, they will be sad."
