Xueba, I beg you to go and escort him quickly!

……

If n has a representation, the number of items is even, and the smallest term is K+1, then this representation can be "extended" in the negative direction...

……

则n的表示法有（a1+1）（a2+1）…（at+1）种.

Solution complete.

Xu Heng wrote very quickly.

Swish!

There is no pause at all.

"Crack!"

After taking the photo, I immediately sent it to the group, and then Xu Heng threw his phone on the table, and he ran to the bathroom.

Very anxious.

A question was posted in the group, and it took 5 minutes until Xu Heng finished answering it!

Even if Xu Heng searched the Internet and copied the answers, it would not be so fast!

And judging from the standard answer, Xu Heng's approach is a little different!

Lord,"!!!"

Crowd management, "!!!"

Members of the crowd, "!!!"

"As expected of Xu Heng!"

"This is too fast! Don't you need to think?"

"Damn it! It's true! The answer was given so quickly? I searched the Internet and just found the answer to the question."

"Faster than finding an answer!"

"Isn't this human? Have you ever encountered such a perversion?"

"No...but I have encountered the feeling when doing this kind of topic!"

"When I was in elementary school, everyone was doing multiplication. One by one had to list the formulas and multiply one by one. I used a simple method and quickly gave the answer."

"I have already mastered that method, so I quickly gave the answer."

"I think Xu Heng should be like this too!"

Use elementary school multiplication skills to describe Xu Heng's skills in doing Olympiads?

Everyone was dumbfounded.

But looking back, I couldn't refute it.

"." @许健大大!Please accept my knee? "

"@许健大大, I am really convinced! I am so impressed now!"

"@许健大大? Are you so cold? Why don't you talk?"

"@许健大大?!"

Although the group message is not prompted, but if someone @, there is still a reminder.

"Ding! Ding Ding!"

"Ding ding! Ding..."

keep ringing!

Yue Pingting took a look, "?"

It happened that Xu Heng came back.

Yue Pingting, "Someone is looking for you."

Xu Heng picked it up and took a look, "It's group news, these guys have been @我."

Yue Pingting leaned over, "This group of guys?"

Look at the group name again:

【Xu Heng Fan Alliance】

"Fan group? Where did you get the fan group! No, I want to join the group too!"

"You secretly have a fan base!"

Xu Heng, one head and two big, "This is not a fan group!"

Yue Pingting pointed to the group name above.

Xu Heng, "I said this is someone else's group, do you believe me?"

Yue Pingting nodded, "A fan group created for you! I believe it! Let me see! God! There are more than 50 people!"

Xu Heng, "..."

Yue Pingting, "I want to join the group! You still manage, just pull me!"

Xu Heng looked at Yang Kaixuan, "Please explain to me!"

Yang Kaixuan, "Explain what? Seeing is believing!"

Yue Pingting, "That's right! Seeing is believing!"

Xu Heng, "..."

Yang Kaixuan, "Although you are originally a group of classmates who participated in the Mathematical Olympiad in the whole province, everyone admires you very much!"

Yue Pingting, "Just... wait!"

Her expression changed instantly, and she looked at Yang Kaixuan suddenly, "What did you just say? What group was this group before?"

Yang Kaixuan, "Students from all over the province who are going to participate in the Mathematical Olympiad!"

Yue Pingting immediately shrank her neck, "No more, no more!"

How could she be qualified to join in!

She dare not!

She is cowardly!

"Just pretend I didn't say it!"

(promised good)

"hiss……"

Even she herself was shocked by Xu Heng.

Although he knew that Xu Heng had reached the pinnacle of mathematics!

But being surrounded by a group of top students participating in the Mathematical Olympiad and regarded as idols was something she never expected!

Those are the top math masters in the province!

They were all fans of Xu Heng!

They are not ordinary students!

All of them are academic masters who are proud of their talents!

Some were even escorted!

But in this group, everyone has to sit cross-legged or lying down.

Yue Pinting looked at Xu Heng.

Xu Heng, "Is there a flower on my face?"

Yue Pingting, "You can always surprise people by surprise! Although I am numb, you always have new tricks!"

Xu Heng rolled his eyes, "I don't like hearing your words! Did I do this? What does it have to do with me!"

Yue Pingting stuck out her tongue.

"Ring Ling Ling..."

The school bell rings.

Just let this matter go a little bit.

Xu Heng continued to scan his phone.

Within a few minutes of playing, there was another message @自己 in the group.

Xu Heng didn't bother.

But several times in succession, Xu Heng had the urge to close the group.

Click in to have a look.

"@许恒! Did your school look for you?"

"@许健大大! The provincial mathematics exchange meeting is about to start! Have you been invited?"

"There must be him!"

"That's right! It's just a matter of time! We are in the provincial capital, so we will know sooner. Xu Heng is in the county, so it will take time just to convey the news!"

Xu Heng, "What provincial mathematics exchange meeting?"

"Master Xu Heng, don't you know?"

Xu Heng, "I don't know."

"Hey! The group leader, please come out and explain! You are also a person who has participated several times!"

PS: Thank you [Reading Fatty] [tail number 1522] for your support!

Chapter 150

Group leader: "That's right! This meeting is organized by our province and the two surrounding provinces to promote learning progress among students."

"On the surface, it seems to promote learning progress!"

"But everyone knows that this is a secret battle of mathematical prowess!"

"And this time the two provinces next door, in this year's Mathematical Olympiad, one team No.2, one individual No.3, they will be even more arrogant!"

"..."

"For a long time, our province's college entrance examination papers have been more difficult than those of the other two provinces. They have always reminded our province that it is not that the test papers are difficult, and that students can learn better and take more exams. Wait or something..."

"..."

Xu Heng saw it.

This so-called exchange meeting is nothing more than a competition of talents and education at certain levels among the three provinces!

But Xu Heng was curious, "Shouldn't this be a comparison with college? Why did it involve high school?"

The group owner was helpless, "We don't know very well, I have participated in it twice."

"Actually, the time for the real exchange of mathematics is only half a day, and it is more of an all-round competition."

"I heard from the teacher who led the team. It seems that this involves the funding of high school education in our three provinces!"

"Anyway, no matter public or private, you can't lose!"

"Master Xu Heng! The province will definitely look for you this time!"

Xu Heng hasn't finished reading the group news yet.

The principal has come over.

"Student Xu Heng!"
