I'm a street kid, and my beautiful wife doesn't want a divorce!

In this era, children do not have computers or mobile phones to study, and there is little information.

Students can only rely on textbooks, and there are relatively few decent review materials.

For the college entrance examination, there are no mountains of test materials.

In addition to textbooks, candidates have very few teaching aids. Schools do not uniformly order materials, and candidates generally buy them themselves.

At that time, most families' financial conditions were not very good, and buying books was a luxury.

Buying one or two copies in a bookstore is like finding a treasure.

The college entrance examination of this era is relatively easier than that of later generations, but again, there are no tutoring classes or tutoring materials. Compared with the candidates of this era, the college entrance examination is still difficult. It is a real army crossing a single-plank bridge.

Liberal arts subjects such as Chinese and history are fine, but at worst it's rote memorization.

Mathematics, Physics, and Chemistry are difficult. Science requires practical practice. It is useless to study questions and test papers and just rely on a few example questions in the textbook.

Li Daya's son Xiaohao locked himself in the room and scratched his head.

The teaching conditions in the provincial capital are good. The school has a mimeograph machine and steel plates, and the test papers are mimeographed on wax paper. The teacher gives each student two sets, no more.

For science, Xiaohao has no talent advantage and relies mostly on hard work.

But there are some questions that I really don’t know, which cause headaches and make my head explode.

He was so angry that he smashed the table and felt very irritable.

This shocked Li Xia and the others outside. The table must hurt if they hit it so hard.

Li Daya didn't dare to knock on the door to ask her son to eat. She couldn't help at all with the matter of studying, so it all depended on her own efforts.

Chu Mengxi said:"Sister, let me go and call him. You can't just study and skip meals."

Li Yan came out of the kitchen and put the dishes on the table.

He glanced at the door, shook his head and said:"This is just studying, Daya, don't let your son get crazy by then."

Ding Qiuxia patted Li Yan on the back, glared at him and said:"You crow's mouth, Xiaohao studies so hard, it doesn't matter if you don't sympathize with him, you curse him!"

"It is."Li Yan muttered in a low voice. These days, it's not uncommon for people to go crazy reading.

Li Daya put the bowls and chopsticks away and said,"You guys eat first, I'll call him."

Li Daya walked over, did not dare to knock, opened the door gently and went in.

A few seconds after entering, Xiao Hao's excited voice came from inside. Without saying a few words, Li Daya shook his head and came out of the room.

Everyone looked towards Li Daya looked over and the latter smiled bitterly and shook his head.

"This kid couldn't solve a math problem about a function. He had to solve it before he could eat, so he was in trouble."

"Let's eat first, I'll leave some food for him.

Li Yan shook his head:"What am I talking about? I got into trouble with the question. What's the matter? I can't solve the question. Do I still have to fight with the question? Isn't this crazy?""

Li Xia helped the two milk dumplings pick up vegetables and said with a smile:

"This is called the perseverance and research spirit of scholars. Those who have not read the book should not talk, as they will not understand. Li

Yan glanced at Li Xia and said dissatisfiedly:"Hey, you are talking as if you have read a book. I am still in junior high school for one year. You have not graduated from elementary school, and you are not qualified to speak." Ding

Qiuxia nodded and said,"I think what Li Xia said is right. The persistence and research spirit of a scholar are incisive." Li

Yan became even more dissatisfied. He glared at his wife and said,"Hey, that's not bad!" You are a woman, what do you know? It's still incisive, but not fart. Li

Daya held up his forehead and said,"My son is enough for me to worry about. Brother, can't you just calm down and eat quietly?"

Li Yan:"Hey, why are you just talking about me? Li Xia, why don't you talk about him?""

Whoosh!

Suddenly, Li Xia stood up.

Li Yan was startled and dropped his chopsticks on the table.

"What are you doing, standing up suddenly, scaring someone to death!

Li Xia smiled:"I'll ask Xiao Hao to come out for dinner." Li Daya quickly stopped him:"

No, it's useless if I go, he's upset."……"

Li Yan said from the side:"That's right, your sister can't even scream, and you can't do anything. Just eat well and don't make any trouble.""

"He didn't eat, his stomach was empty, and his head lacked energy to think. It was useless to continue like this, and he couldn't solve the problem."

Li Xia patted Li Daya's hand, gave him a reassuring look, and said,"Sister, don't worry, I can call him out."

Li Yan looked unbelieving:"If you can call him out, I will eat it with chopsticks.""

Li Xia laughed and walked into the room. (To read Baoshuang novels, go to Feilu Novel Network!)

In the room, Xiao Hao held his head with both hands, held his hair with his fingers, and stared at the test paper, motionless.

Li Xia Walking over, he didn't hear anything.

The wax paper test paper on the table was full of dense mathematical questions.

【If the image of the quadratic function yx2+bx+C passes through the point (-40)(2,3), what is the expression of this quadratic function? ]

It was this fill-in-the-blank question about functions that made this kid rack his brains.

Li Xia smiled slightly. Although he didn't study much when he was a student, after he became rich, he fully understood the disadvantages of being uneducated, so he specially hired tutors to learn cultural knowledge. He learned everything he had never learned before.

The college entrance examination questions in this era are relatively simple, they are all basic versions, straight to the point.

Li Xia glanced at Xiaohao's draft paper and said with a smile:"You are solving the problem in the wrong direction. The subfunction passes through a fixed point or has nothing to do with the value of a certain letter. You have to combine all the items with that letter first. Then. Let all expressions before the letter equal zero……"

Li Xia stood behind Xiaohao, with his hands behind his back, instructing him like a teacher.

"It has nothing to do with the value...all items are merged...oh, why didn't I think of that?!"

Xiao Hao was still immersed in thinking. Li Xia's voice came not from his ears, but from his brain.

Even Xiao Hao didn't know that Li Xia was standing behind him.

Rustle!

Xiao Hao was suddenly enlightened. Thoughts came to me all of a sudden.

The steps to solve the problem were instantly filled up on the manuscript paper, and the answer was finally settled.

"call~！"

"Finally figured it out~！"

Xiaohao was relieved and his face was full of joy and pride in cracking the answer.

"Okay, now that the problem is solved, it’s time to go have a meal."Li Xia reached out and patted Xiao Hao's 823 shoulder.

"ah?!"

Xiao Hao froze, and then he realized

"Uncle, when did you come in... Hey, it was you who was talking just now……"

Li Xia shook his head:"You kid, you take the questions too seriously. Sometimes you have to relax your nerves. You can't just stay focused. Change your thoughts and ways of thinking, you know?"

Xiao Hao nodded, his face Shock written all over it

"Uncle, do you still know mathematics?"

Xiao Hao has been studying alone since he was a child. No one around him can help him because he has never read a book.

The idea given by Li Xia just now is very clever, allowing him to solve the function problem that he couldn't solve after two days of hard thinking. , the answer came out all at once

"Understand a little bit."Li Xia smiled.

Xiao Hao knew that Li Xia was being modest, and he still had some understanding of it. On the question just now, he was much better than him.

"Uncle, please help me look at this question. Is my thinking wrong again?"

Xiao Hao became energetic and asked expectantly.

"Eat first. My uncle is hungry. He will study after eating."

"Okay, eat, eat, uncle, it’s rare for you to come to my house, I must entertain you well……"

Xiaohao became both polite and respectful towards Li Xia.

Li Xia brought Xiao Hao out and saw the boy's face full of joy and smile.

This confused several people in the living room.

They all looked at Li Xia in unison. What method did he use to invite this Bodhisattva out?
