"You can make a one-dimensional quadratic equation?!!!" Hong Tao's father immediately spoke neatly when he heard the math.

"But try!" Hong Tao looked at his father with a smile.

"Then try it! Principal Liu, you can come up with the question, I really can't grasp the things in junior high school. Hong Tao's father saw Hong Tao's smiling appearance, he knew that his son was sure, when he talked to himself about self-study, building a house, and talking about making earth heating, it was this virtue, in order to avoid suspicion, he handed the pen to another colleague.

"Junior High School...... Well...... I want to think about it...... That's it...... "The thin teacher Liu picked up the pen, pondered for a while, and wrote an equation on the paper, in fact, he didn't need to think about it to write a question casually, what he pondered was how to write a relatively simple question, don't embarrass Hong Tao's father too much, and he didn't think that a child of a few years old could solve a one-dimensional quadratic equation.

4（x－5）^2=16

"It's easy, I'll write down the process!x=3 or x=7. "The reason why Hong Tao chose the question of the third year of junior high school is because he didn't do much in high school, and only the things in the third year of junior high school have the deepest memory.

"Oops...... Teacher Hong, this son of yours is amazing! This is to take over your class! Quick thinking, every step is correct, and the format of disintegration is correct, you tell us, how do you teach your son! Even if he can speak and start teaching, this is three years! After five years of primary school, and three years of junior high school, this ...... This is almost a prodigy!" Before Mr. Liu finished writing the disintegration process by Hong Tao, he already knew that Hong Tao would do this question, and he was so shocked that he couldn't wear his glasses, so he took it in his hand and wiped it with his clothes.

"I'll try a question too!" The vice principal couldn't help it, his brain was a little red with excitement, he snatched the pen from Teacher Liu's hand, and lay on the table to write.

[The procession had 8 rows and 12 columns, and later 69 people were added, so that the number of rows and columns added by the procession was the same, and how many rows and columns were added]

This is a problem of a quadratic equation, which is much more difficult than the previous one, not only to solve the problem, but also to understand the problem, and also to involve the knowledge and comprehension of the language.

"x=3, added 3 rows and 3 columns. Hong Tao wrote out the disintegration process on a piece of paper and finally worked out an answer.

"It's too early to say whether a prodigy is a prodigy, anyway, it's the first time I've seen a child who hasn't yet entered elementary school can do the third year of junior high school so neatly and correctly! Teacher Hong, your child must be cultivated well, there will be great development in the future, if you can be admitted to our school, it will be even better!"

"You're saying a bit too far, he has to finish elementary and middle school before he can get to university, and it's hard to say what it will look like at that time. Although Hong Tao's father said it very modestly, he never lit a cigarette in his two hands, and now he is about to crush it.

Hong Tao finished these two questions, while everyone and his father discussed their future exhibition problems, quietly slipped out of the study, and then ran to his grandmother's house to hide from the leisure, at this time the study is too dangerous, 5 or 6 university teachers are eyeing up to prepare a question to test themselves, can no longer fight with them, otherwise their old bottom will soon be tested by these professional judges, they do a job every day.

Once the bottom is leaked, then his fate will be worried, according to his father's temperament, 100% will send him to that kind of juvenile class, although Hong Tao is not sure if there is that kind of juvenile class run by the university now, but only as soon as it appears, he will immediately go to be with those precocious freaks, and live a hard life in the mountains and seas, and there is no future. That kind of juvenile class has been proven to be basically useless in later generations, and it seems that none of the people who won the Nonell Award learned it from the juvenile class.

The reason why Hong Tao showed his little hand in front of his father's colleagues and leaders and surprised them was mainly to make the leaders of his father's school more impressed with his father, and it was best to remember him. In fact, this is also a disguised sycophant, and gifts, giving things is not fundamentally different, the father's social skills are too poor, and too many tribulations make him afraid, relying on persuasion must not be persuaded, so he has to go out by himself, forcibly let him first Jane in the emperor's heart, let the leader remember that you are better than the leader can't remember who you are, as long as it is not because of bad things.

However, the father seemed to feel that his son had not shown all his advantages in front of his leadership colleagues, so the design drawings of the family heating were also taken out by the father as his son's report card and put in front of everyone. Although these teachers were teachers, they were the most proficient in this kind of design scheme, because the main task of BJ Iron and Steel Institute at that time was to train various college students for steel, and for this purpose, many courses related to steel manufacturing were also offered.

Soil heating is actually a simple small boiler and a hot water circulation system, which is entry-level knowledge in the steelmaking industry, these teachers know a little bit, even a math teacher like Hong Tao's father, can use mathematical formulas to prove how efficient the system is. So a few teachers and the vice principal folded their arms and sleeves and began to reverse extrapolate and calculate on the father's small square table, and wrote a large table of proof formulas, and then Mei Zizi left, as if a small academic seminar was held, and gave a final conclusion, the design of the water jacket designed by Hong Tao is small, and the heat absorption capacity is also insufficient.

When Hong Tao came back from his grandmother's house, his father was still stuffy in the study to sort out the table of scratch paper, he said that he found a few good test materials, both practical and teaching, he was ready to summarize it while it was hot, and then put it into his future teaching content. Although his father didn't say anything to Hong Tao, seeing him smoking cigarettes one by one, Hong Tao knew that he was very happy, and the change in his father's feelings was easy to see from the surface.

Whenever he smokes cigarette after cigarette, he is either very angry or happy, and according to today's situation, he should not be the former, that is, he is happy. However, Hong Tao has some opinions about his father's method of expressing his feelings, and he will definitely bring more joy and anger to his father in the future.

In general, the Spring Festival of 77 years Hong Tao is still relatively comfortable, his own family and grandfather's family have increased the housing area, and they have also used more efficient, cleaner, More environmentally friendly earth heating, whether it is relatives or friends, as long as they come, the first is to praise the house, the second is to praise the soil heating, the third is of course to praise Hongtao, grandpa does not want to be so subtle as his father, as long as you look at a radiator more, he will immediately carry his grandson out, from a certain action when he can't speak and talk to you, until the Ming Chuang zào of earth heating, first prove that his grandson is extremely smart and clever, and by the way, it also proves that his doting is actually a discerning eye, not doting, is Bole.

There are always two sides to things in the world, one side is good, and the other side is definitely bad. This principle applies to everyone, and of course to the people who travel through it, because no matter how you wear it, you are still human!

Hong Tao's reputation is getting louder and louder around his home, which is mainly the credit of Hong Tao's grandfather, first self-taught, then to help the family design soil heating, and then to help the two families purchase things, a few years old little fart not only did not cause trouble again for half a year, but also can clearly calculate the accounts, but also can carry a plastic bag, hold a small book, full of buildings and yards door-to-door electricity bills, each household should pay a few cubic meters of water bills, Several kilowatt-hours of electricity bills are calculated accurately, and I know how to round them, and a standard table of water and electricity bills is drawn in a small book, not to mention children, even adults who have gone to middle school.

As a result, Hong Tao was targeted, and trouble followed, and it was annoying!

The person who is looking for trouble, Hong Tao, knows Hong Tao's father, he is Uncle Jin's house on the third floor, and the specific trouble is that Jin Yue. Before the Spring Festival ended, Uncle Jin came to Hong Tao's house to visit the door, and brought Jin Yue with him, this is very abnormal, in order to avoid giving Hong Tao the opportunity to bully Jin Yue, Uncle Jin came to the house to chat with Hong Tao's father, play chess, and came alone.

Hong Tao didn't notice it at the time, his attention was all focused on Jin Yue's doll-like face. In this era, there is no cosmetics, and there is no plastic surgery, regardless of men, women, young and old, it is all primitive, what you look like is what you look like, beauty is beauty, and if you don't look good, you don't look good. Jin Yue and Hong Tao basically represent these two adjectives, Jin Yue is the embodiment of beauty, and Hong Tao is synonymous with not being good-looking.

Although the appearance of a child does not represent the appearance of adulthood, Hong Tao himself knows in his heart, because he knows what he looks like when he grows to 4o years old, he can only say that he is slightly more open than when he was a child, but the main organs have not changed much, especially a pair of eyes, and it cannot be said that it is small, in fact, if you carefully calculate the total area, Hong Tao's eyes are not small at all, but the plane layout is not very good, the top and bottom are too narrow, the left and right are too long, you can see it if you don't smile, a smile is a fox, and it is difficult for others to treat you as a good person.

And Jin Yue is the opposite of him, people's eyes are big and round, the eyelashes are not long, but also naturally upturned, in the blink of an eye, they are like two big brushes, flickering, looking particularly cute, in addition to her self-curling, the roll is particularly moderate, neither want Africans to be like the same as steel wire, nor do you want some people to be like that, except for the mess of the head, basically can't see any beauty. Her head is like a scalded wave, straight and springing back, straightening and springing back, not changing at all.
