As soon as Yang Fan's mobile phone was turned on, there was another text message, and only three people knew the number, his parents and Xiao Hongye.

broadcast my mother's phone and connected: "Boy, you just turned on the phone, you're going to die." ”

Yang Fan stared at the screen in a daze, the number is a number, and it is impossible for him to dial the wrong one, so this is the mother and Xiao Hongye together?

"Goddess, is it in my house?" New York is 9 o'clock in the morning, isn't it supposed to be 11-12 o'clock in the evening.

"Auntie is watching TV on the side, she doesn't bother to pay attention to you, and asks the goddess to help answer it. ”

"I'm asking why you're still together so late, and you don't go home and be idle. ”

"Young man, if your finishing ability is half of your mouth cannon ability, you don't have to worry about aunts and uncles. I've inquired for you, there are more than 20 media lurking in your community, and they have dug up all the cruel things that trampled you on ants since you were a child. ”

Yang Fan disdains it, cares about such a trivial matter as killing ants all day long, and has the ability to inform the whole country about his open urine.

"Then my parents live in your house?"

"No, there is a property outside, and the goddess helps take care of one or two by the way. ”

With the status of the Xiao family in Wuzhou, and the absolute safety of his parents, Yang Fan praised Xiao Hongye's methods, thinking of the matter of the paper, it was rare to be serious, and his tone became serious: "Goddess, please help take care of it for a while, the outbreak will be bigger in a few days." ”

"How big?"

"The earth will shake three times. ”

Xiao Hongye took a big breath, Yang Fan nodded, Xiao Hongye's major events can still be distinguished clearly, and his character is still gone.

"Young man, do you want to go to the earth, with a spasm in the body, everything is tasteless. ”

Yang Fan almost popped his mobile phone, and talking about business was crooked to this extent. Where is the bottom line, no wonder other classmates say that Xiao Hongye likes to talk about yellow jokes, and Hangsi finally saw her true face.

"How far is my mom from you?

"I'm in love with you on the windowsill, of course Aunt Song is very conscious. The goddess suddenly found that her aunt had a strange brain, and the goddess had just touched the doorway. Talking to her about "The Legend of Chu Jiao", many plot routines have been analyzed by your mother, all non-dragon men who appear, even if they are enemies, will fall in love with the heroine, the plot is guessed nine times out of ten, it is worthy of being the god of female frequency development back then, and many plots turned out to be leftovers from what she played back then. ”

"You know even that. ”

After the family banquet that day, Yang Fan also specially inquired about his mother's author number and refreshed his three views. My mother can only write brain holes, more than a dozen books start with 50,000 to 100,000 words, the plot is wonderful, but there is no way to continue, this eunuch.

The character was lost, and the vest was still picked up according to the writing, and he didn't dare to dive from then on.

Thinking of this, Yang Fan was stunned, the big thing was actually taken crooked by Xiao Hongye again. slapped himself hard, and scolded angrily: "First of all, my parents should also ask for leave when they go to work." It's really big. ”

"Boy, the goddess has a phone call from a little rascal in the United States......"

"Little rascal is useless, hang up, thank you goddess. ”

Every time after bragging with Xiao Hongye, Yang Fan felt very relaxed, this phenomenon was very strange, and the other party seemed to have a funny aura.

——————

Personnel from more than 100 countries have arrived, and the International Olympiad has finally begun.

In order to show the importance of the Olympiad, the entire hotel was chartered by the organizers, and there were two or three thousand visitors from all over the world plus some media.

I have to say that the International Olympiad has also attracted more and more attention from Western countries, and countless mathematical geniuses who have reached the apex have started to rise from the Olympiad.

This is a competition between the younger generation of the world, and even the DPRK countries, which have less than a pot of urine with all the countries in the world, have sent people to participate.

Most of the hotel's meeting rooms were emptied, desks were set up, and the countries that made soy sauce were assigned to remote locations.

The veteran strong team will be concentrated in one place, under the eyes of dense cameras, monitoring probes, and on-site supervisors.

On the first day, the opening ceremony passed with great excitement, and at eight o'clock on the second day, all the students were in place.

The rules of the Olympiad are written by the home country, and the teacher who leads the team translates them into the Chinese language and gives them to the students.

Every time the teacher leads the team, he must be proficient in the Chinese language, otherwise he will not even be able to translate the topic, and his face will be lost internationally.

Teacher Qian got the question, quickly translated Chinese, printed the paper, and after several verification procedures, the staff distributed the paper to the six students.

The seats are naturally randomly assigned, and Yang Fan is in the middle section, left and right, with all kinds of skin colors and races.

At the beginning of the live broadcast, the students lowered their heads and checked, and in four and a half hours this morning, there were only 3 questions.

Question 1: Let I be the inner ...... of the triangle ABC Verification: Triangle RIS is a sharp triangle.

Yang Fan's eyes narrowed and muttered: "It seems that there are not many tricks in high school mathematics, it depends on whether the idea can find that little bit of inspiration." It seems that it is not as difficult as the missile positioning geometry problem that I did during that training camp. ”

Obviously, the students present are all among the top in the country, and it is not necessarily worse than the other.

As soon as Mr. Qian sat down, Mr. Zhou beside him couldn't wait to bite his ear and said, "How difficult is the question this year?"

The title was translated by Mr. Qian, who is a veteran who can naturally recite it after reading it and deduce the difficulty. After thinking for a moment, Mr. Qian said: "The first two questions are in the normal range, and among the six people in my country, I estimate that 5 people must have done it, which is the third question......"

"How's it going?" Mr. Zhou's whole body tightened, and he almost screamed.

The on-site supervisors glared at him.

Any movement can interfere with students' train of thought, irrelevant personnel are cleared, the media can only put down cameras and leave, supervisors can only move around, and can only monitor students' behavior through surveillance.

Turn off your mobile phone when you enter the scene, and try to communicate with gestures and eye contact.

"It's a little wrong, it looks like the question is wrong. Teacher Qian frowned, every time the Olympiad is a country with English department, Teacher Qian is a part-time translator for the team leader, and he has been in contact with the Olympiad questions for 20 years.

Many times, he can immediately deduce the result by looking at the problem, and even the student can estimate how much time it takes.

"You can't get the title wrong. "Mr. Zhou is also an expert. Americans attach more importance to this aspect of academia than other countries, and such a big joke will spread around the world for decades.

Moreover, the United States has also held it several times, and with this experience, the question process must have been verified by many parties.

"Even if it's wrong, it's okay if everyone scores the same. Mr. Qian comforted himself that for the first time he encountered a problem that even he was embarrassed by, he quickly took out a pen and paper to check it on the spot.

There was no sound at the scene, and for two hours, Mr. Qian was still struggling with the last question, and cold sweat broke out on his forehead.

"Still can't do it?" said Teacher Zhou.

"It seems to be wrong. Teacher Qian looked around, the team leaders who represented the country were also stupid, and the primary half of the students at the scene looked ahead with blank eyes.

"That's a weird question. Yang Fan bit the pen and fell into deep thought.

The graph is very simple, the triangle ABC, AC and BC line segments have two points of D and E, the angle EAB is 70 degrees, and the angle is ...... 10 degrees, find the number of X angles.

"It's a junior high school triangle, could it be that simple?"

The graphics are clear at a glance, the conditions are simple, and the first reaction is to take the wrong volume.

Yang Fan didn't care, he did it slowly according to the train of thought, and wrote:

∵ sum of the inner angles of the triangle is equal to 180°∠AEB=180°-∠EAB-∠EBA...... ∴x=50°

In less than a minute, he worked out the answer, without any hesitation or pause.

"Absolutely impossible, another way, just verify the answer. ”

∵∠CED=∠ACB+∠CDE...... ∴x=60°

The two answers were very simple inferences, the thinking was very smooth, and the hands did not stop, and they came up with completely different answers.

"This ...... What's going on?"

The third time, and then calculate, but to get a 40°.Three three methods, looking at the jitter is very simple, but the answer is not the same at all.

Yang Fan was a little confused, and he was also wondering if the topic was wrong.

He looked up and saw that the students and teachers were biting their ears again, but the Americans in front of him were unusually calm.

"There must be a solution, Americans are showing off their IQ. Exercise. ”

After thinking about the topic carefully, after twenty minutes, he finally understood.

"It turns out that what is the degree is to mislead people, to use the proportion of the length of the line segment to calculate, a lot of work. ”

He scribbled several chapters on scratch paper, and the amount of calculations was simply the highest in any high school math.

The answer turned out to be 35°.

When the question was finally completed, he clicked on the next step, and it took 64 steps.

"Awesome. Yang Fan thumbs up, this is algebraic geometry, there is a group of math practitioners, who are born to show off their IQ.
