Regarding mathematics, Lu Ye's self-confidence is even more than poetry. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 Although Lu Ye has been in Yingchuan Academy for a short time, there is still a gap between his attainments in poetry and writing and the works of those sages and great powers that he remembers in his mind.

This thing needs talent, although Lu Ye's talent is good, but there is still a gap between him and those real geniuses.

But the math is different.

The mathematics mastered by Lu Ye was the most advanced in the entire era. No one dared to say that mathematics would be better than Lu Ye.

Xiahou Nan wanted to compare mathematics with Lu Ye, as if a fledgling technician in later generations wanted to compete with Jobs. Of course, it's just that Xiahou Nan didn't realize this.

Lu Ye made up his mind that he would play more with Xiahou Nan when the time came.

Xiahou Nan took the lead in asking the question, which was a simple problem of chickens and rabbits in the same cage. In fact, the chickens and rabbits are in the same cage, for these people present, it is still a very difficult question, and it is not easy to make a very simple answer.

However, such a problem falls into Lu Ye's hands, and there are simply not too many ways to solve it.

In less than ten seconds, Lu Ye mentally calculated slightly, and the answer had already come out.

"Thirty-one chickens and ten rabbits."

As soon as Xiahou Nan finished finishing the question, he was still a little complacent, he had thought about this topic for a long time, and finally came up with the result through a very complex calculation method. But he didn't expect that in front of Lu Ye, as if there was no difficulty at all, it was solved almost instantly.

"This ...... How did you guess that? Xiahou Nan couldn't believe it.

Lu Ye had an unfathomable smile on his face: "This is not a guess. Then he pointed to his head: "Sometimes, this is what you need." ”

Xiahou Nan said: "How did you make it?" ”

Lu Ye was secretive: "The Buddha said, don't say it." ”

During the Eastern Han Dynasty, it was the time when Buddhism was introduced. Xiahou Nan also doesn't know much about this kind of thing. But he also understood that this hand should be Lu Ye's secret ability, and he asked him in front of the public like this, of course he wouldn't tell himself.

So although his heart was like a hundred claws scratching his heart, Xiahou was stunned and didn't express it on his face at all. Calmly said: "Arithmetic will not deceive, since you can say the answer, then of course you have solved this question." Now it's your turn. ”

No matter what Cao Zhen and Cao Fu think of Xiahou Mao, based on Xiahou Mao's demeanor today, if it weren't for Lu Ye's preconceived ideas, maybe they would have become very good friends with Xiahou Mao.

Lu Ye thought about it slightly, and a good idea came out of his mind.

Later generations of netizens have made a summary of the math problems they have done, and they are always in the water and out of the water, and they are never satisfied with the swimming pool. Cars that always walk from one end to the other, but don't know when they met. always set off before Xiao B for a period of time, but there were always various accidents on the road, and finally Xiao A caught up.

……

These things can be said to have accompanied the reading era of young people in Lu Ye's area.

And the question that Lu Ye wanted to give Xiahou Nan was unfortunately one of them.

"It shouldn't be very difficult, although I want to save some face for him, but I can't let myself be embarrassed......." Lu Ye said to himself in his heart.

If Xiahou Mao also answered his own question instantly, then the gap would not be obvious.

Thinking of this, Lu Ye groaned slightly and chose a topic.

……

"A pool...... One head in, one end out...... The flow rate is ...... The outlet aperture ....... ”

However, as soon as the question came out, many of the people present showed blank expressions on their faces.

"What's this problem?"

"Who would do such a brainless thing? Wouldn't it be okay to plug the other end? ”

"This question doesn't make any sense at all!"

But it was such a meaningless topic that made Xiahou Nan frown and fell into deep thought. Do math problems need to be meaningful? Lu Ye scoffed, the math problem itself is the greatest significance.

……

Even Cao Zhen and Cao Fu on the side were frowning tightly at this time, thinking about this topic. Of course, they wouldn't make a mockery of Lu Ye, but they were also confused in their hearts. But more of an admiration for Lu Ye.

"Look at Xiahou Nan's appearance, thinking that this topic is definitely not a simple thing for him." Cao Zhen looked at Xiahou Nan's expression, and knew that Lu Ye's topic was extraordinary.

Although he didn't understand it himself, it didn't prevent him from admiring Lu Ye.

Cao Fu also nodded excitedly, still a little curious: "How did you know Zihang?" ”

Cao Zhen smiled: "This is another very long story...... ”

"Let's talk about it~." Cao Fu was a little curious.

Cao Zhen then told Cao Fu how he met Lu Ye, how he thought about worshipping Lu Ye as a teacher, and how he finally built a paper mill together.

When Cao Fu heard this, he also breathed a long sigh of relief: "The process of getting to know Zihang is really ...... Good luck. If Zihang's temperament was a little different, he might not be here today. ”

Cao Zhen nodded: "But that's what things are, how can there be so many ifs." ”

Cao Fu said: "Anyway, Zihang is on the united front with us now, otherwise it should be us who will be anxious." ”

Cao Zhen nodded slightly, with Lu Ye's ability, sooner or later he will be noticed by these people in Xu Ducheng, and when the time comes, no one knows when Lu Ye will be tempted.

Maybe you'll stand on the opposite side of yourself.

……

Xiahou Nan frowned at this time, constantly thinking about the solution to Lu Ye's problem.

Although such a question is unlikely to appear in real life, I have said before that I can ask questions at will, and I have not imposed too many restrictions on this...... But he didn't expect to shoot himself in the foot. Xiahou Nan sighed in his heart.

What should the correct solution look like?

Time kept passing, and Lu Ye looked at Xiahou Nan's expression, and he also frowned slightly at this time.

"Is this topic too difficult?"

"Not really...... This is the ...... of primary school topics. ”

"When I was in elementary school...... Well, I can't seem to make ....... ”

Lu Ye looked at Xiahou Nan's expression, which was about to drip water, and sighed in his heart, it seems that he didn't grasp the degree...... Is this really that difficult?
