Genius Fundamentals

"Who?" Lin is not sure.

The solution was stunned and said: "It seems a bit strange to your home. You don't know what your dad did before?"

"Park administrator."

“Before this?” The solution is thoughtful. “You didn’t feel weird, Teacher Lin... then...one, but a park administrator?”

Lin Xia a little want to laugh, what is "so... one person..."? It is very interesting to comment on Lao Lin, but she still said: "There are people who have their own aspirations. Teacher Lin is bleak and wants to be a wild crane."

"The wild crane is a ghost."

Speaking of Lao Lin, the little solution teacher did not have the leisure time to settle down, and it seems that there is still some shadow in my heart.

"Small solution teacher... You have a great opinion on Teacher Lin." She moved her eyes to the book in the hands of the solution and asked, "What is going on here? Teacher Lin taught at Sanwei University. How do you know?" ”

"Xiao Lin, classmate Lin, don't you know?"

"I really don't know." Lin said.

"Then I can tell you one. This camp was originally intended to invite him to be the head coach, but he refused." The solution was paused and added, "extremely decisive."

Lin Zhaoxi lived, she could not help but think of the phone after the test, Lao Lin is also extremely decisive against her to study in Yongchuan High School.

The old forest of the strawberry world does not have so many "hearts and devils" for Yongchuan...

"So I am still right?" The solution is very meaningful. "Your home is still very strange."

——

During the talk, they went to a self-study classroom on the top floor of the library.

The leader of the team opened the door, a group of junior high school students walked in, each looking for a position to sit down, and then put the book back in her hands, rationalize the clothes, and walked onto the stage.

Lin Chaoxi looked at the unrecognizable back, and expressed his shock at the shameless attitude of "you don't exchange me with me."

Solve the standing on the podium and name your own on the blackboard.

He is completely a college student, but he looks younger than three years ago: "Good afternoon, my classmate Xiaoyan has already introduced me..." He ordered a blackboard. "My name is these two words. Currently It is a graduate student in the mathematics department of this university, and will also serve as the class teacher for everyone this year."

"Small solution teacher is good."

"The teacher is so handsome~"

The lively students were shouting in twos and threes.

"Although our class is a temporary class, you can't see a few faces in a year. But according to the normal component class process, you still need to introduce yourself and understand each other." Solve the first row, "Start with you." ""

"We don't want to."

“I introduce myself to the old soil.”

"What is this to say?"

"Is that word not jiejie, does the small solution mean pee?"

It’s good to die, and the first thing that comes to mind is the four-person group at Yongchuan University.

Lao Wang, A Guang, the lion, and the tiger were one person and one sentence. The last "small solution (jie)" made the whole class laugh.

Lin Zhaoxi could not help but sneer. The second middle school students are no more serious than the primary school students. They are very rebellious and very difficult to engage.

The solution is still smiling, and his eyes flow, shouting: "Lin Zhaoxi classmates~"

Lin dynasty stood up and brushed up, the line of sight in the class gathered together to her, she did not expect that she was just gloating, and the solution actually called her up alone?

"We are old friends, please introduce yourself and give these four students a demonstration." Explain.

Upon hearing this, the four-member group of Yongchuan Middle School suddenly exploded.

"We don't need a demonstration!" Xiaoguangtou said first, "My name is Chen Youguang, Yongchuan Middle School."

"Anhu, I am also from Yongchuan Middle School."

"I, Shiziyang, or Yongchuan Middle School."

"Wang Tianlong is even more of Yongchuan Middle School."

They quickly reported their name and school, and they were "demonized" if they were late.

Everyone in the class laughed again and the atmosphere was very good.

Lin Chaoxi quickly sat down and felt that he had not seen it for three years, and the level of the controller of Xiaojie’s teacher had improved significantly.

——

The next self-introduction session went smoothly. Most people stood up and said the name and the school. Of course, there were also classmates and a serious classmate who introduced their names, schools, hobbies, things and expressions. I want to serve my classmates with a "sincere" desire.

Explain that the "Chen Chu" classmate was seated. Now junior high school is really smart. I know that the link after the introduction is to select the squad leader, so the more you perform in front of the group, the better.

When the last self-introduced student sat down, the class was quiet.

Look at the little face that has become very boring, pick up the chalk on the table, wipe off his own name in the middle of the blackboard, then insert the bag with one hand and start writing.

“Is this the subject?”

"Would you like to start class?"

Behind them came the whispers of the children, and they continued to write. At some moment when the noisy voice reached the peak, he wrote the last full stop and turned and smiled: "Pick up the question, first solve the problem." ”

"Teacher, do you do the problem once?"

"Do you have any conspiracy?"

In the sit-up is the top Chinese school, some people immediately took out the pen and paper, but some difficult children, do not rely on it.

"Otherwise, the students are all big. When everyone comes to the exam, how much hurt?"

After the solution is finished, there is not much explanation.

He began to inspect the entire class, but he was very surprised to find that the four children of Yongchuan Middle School, who were still screaming, were silent after he finished the topic.

They had a contemplative expression on their faces, and then they each picked up the pen and said nothing.

In contrast, students who are still asking "What are the benefits of the teacher?" are not so cute.

"There is no good." Unlocking his hand into the pocket and shrugging his shoulders, "But you have already reported your school name, you should be glory for your alma mater, the first one in front of so many schools in the province, quite Face?"

Involved in honor, the junior high school students who were sitting were instantly motivated, and the last few people picked up the pen and began to answer questions.

Deliberately went to see the Lin Chaoxi side, like the children of Yongchuan Middle School, after he made the question, the girl has already made a quick calculation.

Her neck is low, her white and slender fingers hold the pencil, and she seems to have thoughts and is trying. After all, she is a child who has experienced the cruel and wonderful summer camp in elementary school. It has become an instinct to get the title.

This sense of concentration and struggle is very nostalgic.

Unexpectedly, the line of sight moved to the right and looked at the boys around her. I haven’t seen it for three years, and my classmates have a kind of younger and more handsome.

However, just as he looked at the moment, the classmates of the singer turned the circle and looked up, and looked at him with clear eyes.

The solution smiled and compared it to a mouth shape: "How?"

He didn’t say anything, but he turned the circle again. Then he gently put the pencil in his hand.

——

The topics are as follows:

The two brothers sell a group of sheep. The price of each sheep is the same as the number of sheep. Then the income is distributed as follows: the brother takes 10 yuan first, the younger brother takes 10 dollars, and then the brother takes 10 Block money, and so on, take turns to withdraw money. Assigned to the last turn to the younger brother, but he found that the remaining money is less than 10 yuan, so he had to take the remaining money away, in order to be fair, the brother gave the younger brother a knife, the price is an integer, ask: This How much is the knife?

One minute passed...

Three minutes passed...

Unlocking his arms and watching, just when the minute hand had to turn around, someone finally raised his hand.

"Lin Zhaoxi classmates, very soon."

Many people in the class were interrupted, stopped, and looked at the girl who raised her hand. However, the four middle school students who were closest to the solution were still immersed in the topic and immersed in it.

Lin Chaoxi licked his lips, and some unexpectedly looked at him. The two of them exchanged their eyes, and they nodded, and Lin stood up slowly.

"the answer is?"

"2 dollars?"

There are some surprises.

At this moment, the whole class was quiet again. Most of the students raised their heads and looked at him with uncertain eyes, waiting for the answer.

"Yes."

"The answer should be 2."

"How are you so fast!"

But without waiting for him to speak, the four students sitting in the front row began to say a word to me.

There was a small buzz in the class.

The sound of resoluteness overwhelmed these embarrassment, and he looked at Lin Chaoxi: "Talk about your problem-solving ideas."

"This question seems to be giving up enough information. At the beginning of the sheep, I suddenly asked how much a knife is, it seems to be joking."

"But actually?"

“Actually, if we translate this question in a mathematical language, we can see a lot of hidden information.”

Lin dynasty paused, subconsciously looked down at the book on the table for some years, then looked up and continued: "We can find that the price of the knife depends on the number of sheep, the latter is the only independent in the title. Variable. We have x sheep here, then the total price of the flock is x square. And if the younger brother took n times 10 yuan before taking the money, the change is a, the whole formula becomes..."

Turn around and write down the answer written by Lin Chaoxi on the blackboard.

x square=10n+10+10n+a=10(2n+1)+a

"Then the price of the knife is b, we need to build an equation to make the price of the knife and the price of the change..."

According to Lin Zhaoxi, the second equation was written on the blackboard.

"There is still too much unknown. We can take the model (20) to eliminate n. The next question is the problem of pure mathematics..."

The presence is a very intelligent child, and many people only need time to solve the problem. When Lin said that the model was taken, it was no problem for them, but they still listened carefully to all the ideas.

"What's the idea?" Asked.

“It’s actually quite simple.”

“It takes a little bit of thinking time.”

"To grasp the details of all the information in the title."

"There is also the details in the equation."

I heard this and read it to Lin: "What do you think?"

Lin Daixi showed his expression of thought, and then said: "Two points, don't be afraid of the first, second, translate the text problem into a mathematical language as soon as possible."

"This is the first lesson of today - the question of mathematics, please think in mathematics." The solution is very satisfactory to put down the chalk, watching Lin Chaoxi said, "You are good, the squad leader will do it for you." He said .

The author has something to say: day1.

Tomorrow, my mother still has to have an operation, so I will definitely not be able to update it tomorrow. After this week, it should be much better. I will start to challenge again.
