If you have a question, you have to ask it, so Lin Weiwei stood up: "Teacher, I think there is a problem with question 9!" ”

When the teacher was about to announce that Liu Xiaofeng had won the first place, he couldn't help but be stunned when he heard Lin Weiwei say this!

"Lin Weiwei, what's your problem?" The correction teacher asked.

Lin Weiwei replied: "This question pulls the multiple of three and the multiple of five, but the number of multiples of 3 is pulled once because of 3, and the number of multiples of 5 is pulled once because 5 is pulled once, and it is a multiple of 5 and 3, that is, the number of multiples of 15 is pulled twice because 15 is pulled twice."

Lin Weiwei said the first sentence Liu Xiaofeng saw that there was something wrong, it was a multiple of 3 and 5 twice, and he seemed to have only counted it once?

Lin Weiwei continued: "The other numbers that are not 3 and not 5 are unchanged. We know that even times of pulling remain the same, and odd times of pulling the opposite state! ”

"There are 5o multiples of 3, 3o multiples of 5, 1o multiples of 15, 5o-1o=4o multiples of 3, 3o-1o=2o multiples of 5, 1o-=2o multiples of 15, 1o multiples of 15, 1o multiples of 15, and 15o-=8o multiples of 5, that is, 15o-=8o lamps that are not 3 and not 5!"

"So under the even number of pulls on the light, 1O+8O=9O! There are 90 lights on! ”

After Lin Weiwei finished speaking, the teacher who revised the paper was stunned!

Although it is a mathematics competition, it is still a national mathematics competition, but these questions are not completely new, this question about the lamp is an old problem, and it is estimated that it will be at least seven or eight years!

In the past seven or eight years, the answer to this question has been eighty, and it has been printed on the textbook in black and white!

But Lin Weiwei is right, listening to her explanation, there are really ninety lights on? This......

The teacher who corrected the paper discussed: "Lin Weiwei is right, right? ”

"I also think Lin Weiwei is right, if you don't consider pulling it twice, it's just, this light, pull it once to turn it off, and pull it twice and it will turn on again!"

"Then this textbook ....."

"The textbook is wrong!"

.....

Lin Weiwei watched the teacher announce the results for a long time, so she said, "There should be one hundred and fifty lights in this auditorium, right?" Why don't we try it? ”

Hearing Lin Weiwei's words, the teacher who corrected the paper reacted!

"Lin Weiwei is right, the answer to this question is indeed ninety, and eighty is wrong! Therefore, in this competition, Lin Weiwei answered 14 questions correctly, Liu Xiaofeng answered 13 questions correctly, and Lin Weiwei won the first place in this competition! ”

Hearing the teacher announcing the results, Liu Xiaofeng gritted his teeth, why can't he compare to a play? glared fiercely in the direction of Lin Weiwei, and suddenly thought that there was an international mathematics competition, as long as he won Lin Weiwei in the international mathematics competition, he was still the only genius in the mathematics world!

The top two in the International Mathematics Competition can only participate in the Chinese Mathematics Competition!

After the results were announced, the group from Haruki High School walked out of Mizuki University.

Lin Weiwei won the first place in this competition, naturally there is a bonus, how many awards Lin Weiwei didn't care, anyway, she won the first place and got the opportunity to be sent to university, as for the international mathematics competition..... In a month, she will go to the United States, and Lin Weiwei will have to see if she has time, if she doesn't. She can't go either!

After leaving Shuimu University, Lin Weiwei asked the teacher for leave, Lin Weiwei felt that there was nothing to do after participating in the mathematics competition, she wanted to have a good look in the capital, there is a good saying, if you don't go to the Great Wall, you are not a hero, this capital is here, how can you not go to the Great Wall to wander around?

The teachers also knew that Lin Weiwei's identity was not ordinary, so they did not refuse her leave, and the other teachers and another student went directly to the airport.

Originally, Ye Mingjie wanted to find a reason to go back with Lin Weiwei, but now that Lin Weiwei wants to go around the capital, isn't that just his intention!

In the media, it began to be hyped because Lin Weiwei won the first place in the competition!

Lin Weiwei is a star, if she crosses the gold ...... of a top student

"Lin Weiwei won the first place in the mathematics competition!"

"Lin Weiwei corrected the competition question that was wrong for eight years!"

"He is also a mathematical genius, but he lost to Lin Weiwei"

........

How did it be reported on the Internet that Lin Weiwei didn't pay much attention, now it's not early, Lin Weiwei and Ye Mingjie went back to the hotel first, planning to stay in the hotel for one night, and have a good time in the capital tomorrow! And as soon as she arrived at the hotel, Lin Weiwei received a call from Zhang Xinyi!

"Sister Weiwei, I didn't tell my sister when I came to the capital, if I hadn't read the news and knew that you were participating in a math competition in the capital, I really didn't know you were here!" Zhang Xinyi had a reproachful tone.

"Eh, isn't this afraid that my sister will be busy and disturb my sister!" Lin Weiwei didn't expect this diva to be so enthusiastic.

Zhang Xinyi is full of gratitude to Lin Weiwei, the songs that Lin Weiwei wrote for her caused a storm in the treasure island, and even in Europe and the United States, becoming the best of the best, which made Zhang Xinyi's popularity rise a lot!

Although Zhang Xinyi also brought huge traffic to Tianshang Live, compared with Zhang Xinyi's rising ranking in the international rankings.........

Besides, Lin Weiwei is a producer of classic music, and she has a good relationship with her, but she is afraid that she will not sing in the future?

Zhang Xinyi said: "How can you be so busy, look at your Weibo, you want to release an album?" Do you want your sister to make a cameo in your MV? ”

Lin Weiwei's every song is so classic, and Lin Weiwei's popularity is only higher than that of first-line stars, the sales of this album will definitely not be too bad in the future, and if Zhang Xinyi joins, the sales will definitely increase, Zhang Xinyi just wants to help Lin Weiwei more now, and build a good relationship first, who will ask for whom in the future may not be!

Zhang Xinyi always felt that Lin Weiwei was very special, but to say that it was very special..... Except for a good voice, can write songs, and looks beautiful, there's nothing else, right? But she always has a hunch that it doesn't seem very difficult for Lin Weiwei to ascend to the position of an international diva in the future?

When I heard that Zhang Xinyi wanted to make a cameo in her own album, I was also stunned, if Zhang Xinyi was asked to make a cameo in her own album, although it would greatly increase the sales of her album, but I am afraid it would attract some rumors, your Lin Weiwei's album sales are so high, it is entirely because of Zhang Xinyi's participation!

So Lin Weiwei said: "Thank you sister for your kindness, I plan to release a single album first, and there are not many characters involved in it....."

"Well, are you free tomorrow? Let's play with my sister! Zhang Xinyi didn't expect Lin Weiwei to refuse, but after thinking about it a little, she understood that she didn't force it too much.

ps: Let's finish adding three chapters first, and today's two chapters will be updated in the evening!
