Rebirth 1984 Wife and children are on the hot bed

Wang Xiuxiu smiled instantly:

"Pout again, I won't eat your candy. Even if it is put in the cupboard, it will still be yours from now on. Eating candy will damage your teeth, and later the big fleshy bugs will bite all your teeth."

"Ah, mom, please help me look quickly. Are there any bugs in my mouth?"

The little girl immediately opened her mouth, and Xu Dahai and Wang Xiuxiu were all amused.

At this time, voices sounded in the yard: "What are you so happy about?"

It turned out that the second sister came here with the sixth child, Xu Juan, who was also carrying her dirty and torn book bag, which contained her textbooks.

"When did you come back?"

"Just came back for a while."

"Quick, Xiaohai, please show it to Xiaojuan'er. She is almost crying because she can't solve the math problem. I'm also blind. If you ask me, I can't do it either." The second sister said quickly.

In her eyes, Xu Dahai was a top student.

Although Xu Dahai only graduated from junior high school, he couldn't help but think that other villagers had graduated from elementary school or even not finished elementary school.

If you choose a general among the dwarfs, he will be a top student.

"Fourth brother, look at this question, I can't do it no matter what. My mind is so messed up that I'm about to turn it into a big lump of porridge." Xu Juan, the sixth child, had her nose twitching and her eyes were red.

She is still impatient. The more she can't do something, the angrier she becomes. The angrier she is, the more she can't do it.

Vicious circle.

In the end, I got angry with myself and made myself cry.

"Don't cry. Look, your little face has turned into a big cat." Xu Dahai put down Xiao Tingzi, took the paper and took a look:

"To find the vertex of the parabola of a quadratic function? Wouldn't it be enough to turn it into a vertex expression?"

"Peak pose? What the hell?"

"It's a form of expression of a quadratic function. Now this is a general form.

Let me teach you how to transform it into a vertex form. Can't you tell at a glance what the coordinates of the vertex are? "

What Xu Dahai talked about was very basic knowledge, and of course it was also very important.

Mathematics is a subject that you will find easy if you know how to do it.If you don't know how to do it, you will find it really difficult, and it will be difficult for your second uncle to die.

"For finding the vertex, I remember there is a formula, negative two a divided by b, 4 ac divided by 4 a minus b squared."

Xu Dahai casually wrote the formula on the paper with a pencil. In an instant, in the eyes of the sixth sister Xu Juan, Xu Dahai's figure became majestic, which was simply shocking!

"The number in front of the square of x is a. If there is nothing, it is 1... If you remember this formula, isn't it easy to find the vertex?"

"Ah ah ah, fourth brother, you are so awesome! Is it so magical?" Xu Juan said in shock.

The second sister Xu Mei and Wang Xiuxiu who joined in the fun all laughed.

Only Xiao Tingzi was ignorant, eating White Rabbit toffee and petting the cat.

"That's it. Do you see it clearly? Okay, it's just a lie without practicing. Let's practice it a hundred times first."

"Ah, do you need to practice so many times?"

"Of course, this formula must be memorized firmly without making any mistakes. If you don't practice enough, you won't be able to remember it.

Write it 100 times today, and another 100 times in three days, and you will basically be able to remember it firmly. "

Xu Dahai is very concerned about his sister's studies. In this era, studying is really a very good way out for minors.

As for Xu Dahai himself, he is already 25 years old and has a wife and children.

Besides, he was reborn and firmly believed that he could live a good life without academic qualifications.

Of course, it can even be said that his wish to "live a good life" has been realized.

Now I have more than 17 yuan in cash. If I take the time to go to Yanjing to buy a few courtyard houses, I won't have to worry about it in the future.

"Use your brain to memorize while writing. Don't write mechanically, otherwise it will be of no use no matter how many times you write."

"What do you mean by mechanical writing?" Xu Juan raised her head and asked.

"Have you ever seen a donkey pulling a wheel? When a donkey pulls a wheel, he doesn't think about anything. He just keeps spinning in circles. You can't do this. You have to write and remember at the same time."

"Fourth brother, you're not a donkey. How do you know that a donkey doesn't think about anything when it's grinding? Hehe~"

As soon as Xu Juan finished speaking, the second sister, Wang Xiuxiu and the others all laughed. This time, even the little Tingzi who was petting the cat also laughed.

"Hey, you little girl, your brain will break if you watch me play."

The cold wind is howling outside the window and snowflakes are falling, but inside the house is warm as spring and full of laughter and laughter.

Xu Dahai suddenly discovered that not having a mobile phone, TV, computer, etc. was not entirely a bad thing.

People pay less attention to things on the Internet, and focus more on reality, chatting and chatting with their families, which is ordinary but also has a sense of warmth and happiness.

After playing in the courtyard for a while, the second sister took Lao Liu and left.

Wang Xiuxiu tried to persuade her to stay, but they still didn't eat in the courtyard.

After having a wonderful lunch with his family, Xu Dahai felt tired and lay on the kang, thinking about it and squinting for a while.

Unexpectedly, I fell asleep directly.

When he woke up, it was almost 4 p.m.

There was a strong wind blowing outside the window, wuwuwu~wuwuwu, like a wild beast howling in a low voice, it kept ringing.

He was leaning next to the kangqin, with the heavy orange cat lying on his belly, purring.

He was covered with a military green coat.

The back room was very quiet, and you could faintly hear the voices of Wang Xiuxiu and Xiao Tingzi talking in the main room. In addition, there was the voice of Qimei Xiaohua.

The voice was low, and occasionally there was a chuckle.

Xu Dahai didn't want to get up at all, and slowly closed his eyes. This scene made him feel extremely comfortable, and time seemed to slow down a lot.

After a while.

Just when Xu Dahai was half asleep and seemed about to fall asleep again, he suddenly felt someone pushing him, and then Xiao Tingzi's childish voice sounded:

"Dad, wake up, do you want to eat roasted yams?"

"what?"

Xu Dahai opened his eyes, and what he saw was a large piece of roasted yam. The bright red flesh was shimmering, as if honey was about to flow out.

"Mom just baked it in the kitchen. Don't you like it? Then I'll take it."

"Give it to me and I'll have a taste."

Xu Dahai took the roasted yam and took a bite. It was so sweet and tasted so good.

The fat orange cat's nose was twitching, and when he smelled the fragrance, he immediately woke up and meowed.

He broke off a piece of roasted yam skin and handed it to the big orange cat. The latter smelled it but did not eat it, and continued to bark at Xu Dahai.

"Meow~"

"Hey, it turns out Dashamao isn't stupid. She knows you can't eat roasted yams?"

"Pfft~" Wang Xiuxiu walked into the back room with a smile and said, "How could she not know what you said?"

"Such a big piece of yam, I thought it was not cooked yet, but unexpectedly it was cooked. Is it delicious?"

"It's delicious, very delicious."

"This year, Victory's wife went to the fields to pick up yams. She picked up a lot of them, several bags of them. Yesterday I went to her house to play, and she even gave me dried yams to eat."

Wang Xiuxiu sat sideways on the edge of the Kang, chatting with Xu Dahai about home affairs.
