Liu Lugao talked about it broadly, shining brightly, and he was forced to rise.

"Uncle Lu really has the demeanor of a brick family. ”

"A little bit of knowledge, not worth mentioning. Liu Lu waved his hand, "I don't know that much, just look at mathematics on the boat, net net fish." ”

Liu Sen looked at his expression, and he always skipped that emoji in front of him, what a stud, winning the clubhouse tender model, losing to work in the sea, all of them were distracted.

"Listen to your father, you won the first place in the province, amazing, our Longwan Village has good feng shui, sooner or later there will be an amazing talent, I thought it was me, but unfortunately not, I think it's mostly you. ”

Liu Sen was modest, and saw that the grass was jumping in the net of his cabin, and the strength was very fierce, if he didn't jump away in the net, and see that the weight was at least ten catties, he wanted to buy it, so that his sister could make a whole fish feast, otherwise he didn't even catch a small crucian carp, which was too faceless.

has always carried out the forced that he has blown, and he has to finish his tears when he shouts.

Liu Lu didn't answer, he liked to chat with literate people very much, and said: "High-achieving students, I'll come up with a topic, see if you can, if you can solve it, this big herring has been sent to you, you can't solve it, and I don't want you to do anything." ”

"That's not possible, it's so unfair, Uncle Lu also made some requests. Liu Sen pretended to say that he didn't think that this math veteran could stump himself.

"Then my grandson Xiaojun will go to No. 1 Middle School to study this year, you can take care of it, and you won't tutor it. ”

Liu Sen agreed, and looked at the big herring again.

"An old woman who raises chickens raises a few chickens, accumulates them for half a year, gets a bunch of eggs, is cautious, a merchant comes to buy them, I don't know the number of them, the old woman is afraid that she will lose by counting the wrong eggs, two two numbers, one left, three three numbers, or one left, until nine nine numbers, there is still one left, how many eggs does the old woman have?"

It is said that this should be a nine-element equation problem, and you can always get the answer by writing nine equations, but it is not right to think about it.

After the training of the math league, Liu Sen's mathematical thinking has improved a lot, the logical power of the soul power sub-attribute has increased from 12 to 14, the comprehension has also increased from 15 to 16, the deduction power has increased from 15 to 16, the creativity is still 14, the perception is also 10 has not changed, the self-confidence coefficient is 0.95, and the soul power has reached 86.

But I didn't think of a suitable solution to this problem for a while.

Those one-dimensional two, one-yuan three, two-yuan one, and three-yuan once are not used.

analytic geometry

Infinite series

probability theory

And so on is not appropriate.

Liu Lu is very proud, he can stump Liu Sen, who is a high-achieving student and the first in the province, and he has a sense of achievement.

This is obviously an extremely simple problem, but I can't find a suitable method, let alone advanced mathematics, even elementary mathematics can't be used.

Just like Fermat's theorem, it seems extremely simple, but it took hundreds of years of mathematical geniuses all over the world to succeed it.

Liu Sen responded in his heart, this old guy can't also have a problem.

There was no idea for a while.

The first is to solve the problem.

Since there is 1 left from 2 to 9, it means that the mantissa must be 6 or 1, and the number within 1000 has not been satisfied.

Liu Sen's face was a little dark.

Damn, the math league is all done, is it possible that a fisherman has overturned the boat in the gutter.

Liu Lu said with a smile: "In the past, I asked a few high school students in the village, and a college student, but I couldn't come up with an answer for a long time. ”

The old face smiled into a good chrysanthemum.

What is this question?

Liu Sen asked: "System, can you solve it with spiritual power?"

System: "This question belongs to the category of primary school students, and this system refuses to solve it." ”

MMP, the category of elementary school students stumped me, Liu Sen had a toothache floating in his head with 10,000 grass and mud horses, and his face was hot, I grass, I haven't been so embarrassed for a long time.

"System, can elementary school students answer this?"

"Yes. ”

Liu Sen was so angry that he wanted to jump into the river.

The improvement of the self-confidence coefficient played a great role at this moment, and he quickly remained calm, inspiring his thinking from multiple angles, what is the knowledge of elementary school? addition, subtraction, multiplication and division?

Liu Lu smiled and said, "Don't worry, you count slowly, I'll help you fish." ”

This old guy is at a high level, and he doesn't know how to get it, the fish hook in his hand suddenly turned into gold, threw into the river, a splash floated, and it was a big crucian carp that was lifted up, and he struggled to make a big splash.

What is a flash of inspiration?

In fact, it is the concatenation of thinking, and finally find the best angle in your knowledge reserve system, which is the process of enlightenment.

The least common divisor is indeed elementary school knowledge.

Liu Lu caught another crucian carp.

Liu Sen said: "Just multiply the multiplier relationship from 2 to 9, the smallest result is 2521, and the multiples of the times meet the conditions, this topic is too simple, Uncle Lu, right?"

Liu Lu was stunned for a moment, then laughed and praised: "High-achieving students are amazing, the first place in the province, and work hard to be like Master Hua Luogeng." ”

In addition to the big grass green, Liu Lu caught 3 more big crucian carp for a while, all of which were given to Liu Sen, and he looked forward to it eagerly, and he felt a lot of emotion.

The system prompted that he had generated 300 points of energy.

He rowed away.

Liu Sen muttered: "Uncle Lu, like Hua Luogeng, it is your biggest dream to enter the Tao with mathematics, for the sake of the big herring, I will definitely help you realize it." ”

At this moment, there is no mockery or contempt in his heart, although Liu Lu has always lived out of place, and many villagers talk about his strange behaviors and words behind his back, but he is consistent and does not give up the pursuit, Liu Sen feels that he rows away from the back of a lot of great shores.

What a sumptuous whole fish feast.

After a few days of chic fun at home, Liu Sen will eventually go back, his mother and sister prepare a lot of food, nuts, pickled vegetables and fresh melons and fruits, and his mother is always afraid that he will have less white heads if he uses his brain too much.

In the car to Feicheng, Lin Han personally drove his own car to send Liu Sen and Han Bin there.

After coming to Feicheng, Lin Han took the two of them to eat a meal of Japanese food, and told the two to work hard, when Yuan Bin went to the toilet, Lin Han said: "Yuan Bin may not have a chance to be selected, Liu Sen, as long as you maintain your condition, it is not difficult to enter the provincial team, and the teacher hopes that you can go further." ”

Liu Sen said seriously: "Teacher, I will definitely win the IMO gold medal and take the first place." ”

Lin Han was stunned for a moment, Yuan Bin came back, he didn't say anything, just his heart jumped, maybe there could really be a miracle, I couldn't help but have more expectations, there must always be dreams, what if it comes true? Just like he brought out the miracle with the first batch of students.

After completing the check-in procedures for the two of them, Lin Han returned to Gyeongju.

Yuan Bin came over and knocked on the door, his face was flat, and asked, "Are we mixed with No. 168 Middle School or No. 1 Middle School?"

"What do you mean?"

Yuan Bin had a question that you don't understand, but patiently explained: "Over the years, the mathematics provincial team has been controlled by No. 168 Middle School and No. 1 Middle School, and all the first prizes have been trained this year, and these two schools still account for the majority, and players from other schools will generally choose a camp, otherwise they will be independent, after all, it is painful to have no communication for two months." ”

Knowing that he was fortunate to be selected, Yuan Bin went to various forums and searched the Internet to learn as much as he could.

The first training, choosing which camp to join, the language of the handicap is different.

Liu Sen said: "Look at the performance on both sides, whichever one makes me look pleasing to the eye, add which." ”

Yuan Binxin said, you are the first place in the primary election, you have the capital, I should honestly choose a side, so as not to make it uncomfortable.
