Chapter 49: Jia Qing's Mathematical Enlightenment

Seeing that he was no longer able to match a qualified pair, Lu Zhu showed a disappointed expression on his face and said, "That is the case, that is, Hou Gongzi upstairs and this Feng Gongzi entered the second round of the competition." Pen | fun | pavilion www. biquge。 info”

Although others are unwilling, their skills are not as good as others, so they have to give up. Listen to the answer, and the only second question is what kind of question it is.

I only listened to Lu Zhu said: "My young lady's second problem is a counting problem, from one to one hundred, the one with the least time wins!" ”

Jia Qing was surprised for the second time today, first Hou Hu popped up the word "handsome guy", and now this fairy girl threw out such a "classic" topic. This question can be answered in three seconds by a child in the sixth grade of primary school in modern times!

It's a pity that the people present definitely don't know Gauss this person, after they heard the question, they first did some silent calculations, and after knowing the difficulty, they immediately went to find an abacus and a pen and paper.

The lobby was in a mess, and Hou Hu immediately wanted to go down to find auxiliary tools, at this time Jia Qing said: "Brother Hou don't be busy, I'll give you an answer, you can try it!" ”

Xie Guowei and the others were surprised: "Brother Jia has such a divine arithmetic technique? Hou Hu also said: "Reliable? ”

Jia Qing smiled slightly and said, "Five thousand and fifty, as long as you try it, it won't take long." ”

Hou Hu's face showed hesitation, but he immediately said with an open look: "Okay, I believe Brother Jia once!" Then he shouted into the lobby, "Five thousand and fifty!" ”

There was silence in the lobby, and then many questioning voices rang out.

"So fast? No way, he's blind! ”

That Feng Gongzi also said loudly: "Brother Hou is so eager to say the answer, could it be that he gave up this opportunity and deliberately let Feng Mou?" There was a lot of banter in his voice.

Who knew that at this time, Lu Zhu's voice subverted everyone's thoughts: "How does Hou Gongzi know the answer?" Haven't you counted it before? Green Bead's voice was also shocked.

Everyone couldn't believe it at first, and then they also thought it was Luzhu guessing, although they felt that Hou Hu's shit luck was too much, but then they all felt that they were not wronged to lose, what a boring person must be to do such a boring thing!

In the elegant seat where Jia Qing was, more than a dozen eyes were staring at him, and the gaze in his eyes was so unbelievable.

Xie Guowei said: "Brother Jia really calculated this question before? "Other than that, they really can't accept that people can be so numeracy!

Jia Qingdao said: "If that's not the case, it's just that there is still a door in this, and listen to me slowly ...... for you."

At this time, the green bead girl came up and asked Hou Hu to meet with her young lady, and Hou Hu had to go first.

After that, Jia Qing explained to Xie Guowei and others what the "Gaussian algorithm" was, which made everyone present suddenly realize and admire. Many techniques become very easy when you know them, but before you figure them out, it feels like it's overwhelming.

Just as everyone was discussing other counting skills with Jia Qing, they saw Hou Hu slowly returning to the elegant seat with a sad face.

Qi Chengwu said: "Brother Hou, a good night is worth a thousand gold, why did you come back here with a sad face, did you leave a beauty to come back and eat with us?" ”

……

In a private room on the second floor of Yanyu Building, Lu Zhu said to a woman with a scarf: "Miss, why did you expel Hou Gongzi?" "She had been on the outside, not knowing what was going on inside.

"Humph! You still have the face to ask me, I told you to choose a talented person, and you actually called me a straw bale to come in! When I heard him speak, I felt the urge to beat him up! ”

The veiled woman was the fairy girl, and at this time she clenched her fists and said angrily.

"No, I did exactly what Miss told me, and that Hou Gongzi did answer both questions correctly. Moreover, he answered the second question almost instantly. ”

Xian'er was surprised: "How is it possible?!" No, that would be more indicative of his straw bag, and I asked him how he answered the second question, do you know what he said? He actually said that he did the math, and then he was there to brag about how he had a magical brain, there was no topic in the world that he wouldn't know...... You know, Miss Ben was idle and bored, and it took half an hour to figure out the answer. I thought he was just blowing the conch, but I didn't expect that he was really a real straw bag! ”

Hearing this, Lu Zhu was puzzled: "Then what is the solution to the question he answered?" ”

"Hmph, either he really took shit luck, and he has counted it before, or there are masters around him! It may be difficult to say that there is another way to say this question. ”

Lu Zhu's eyes lit up and said, "By the way, that grass ...... There seemed to be three or four people wearing scholar's uniforms around Hou Gongzi, all of whom looked not ordinary. That Hou Gongzi is from the Xiuguo Mansion, and it is impossible to say that those people are also the sons of several other big clans. ”

Xian'er affirmed: "That's right! It seems that this Jingzhong is really Crouching Tiger, Hidden Dragon, and there are such people who are so indifferent to fame and fortune, they actually look down on Miss Ben, and deliberately let a straw bag tease me! ”

If Xie Guowei and Jia Qing knew that they had inadvertently offended the beautiful fairy girl, I don't know how they would feel. One of them is hindered by the appearance of a beautiful woman, and the other is restricted by age restrictions, so that the beauty of adults is determined. It's not Megumi Yanagishita!

The more Xian'er thought about it, the more she felt that this person was angry, and with a turn in her mind, she decided to think of a way to get out of this evil breath! So he said to Luzhu: "You can arrange for two clever people to keep an eye on them now, and it is best to find out what they are saying, I want to know who is the arrogant person who has answered this girl's question correctly but is not willing to come to see this girl!" ”

"Yes, miss."

……

On Jia Qing's side, everyone was comforting the injured Hou Hu, but everyone knew that they were cheating, and no one said that they wanted to ask for "justice" for Hou Hu.

In the end, Hou Hu was naturally optimistic, and after a while, he said ruthlessly: "Isn't it just that you look down on Hou Ye and have no literary talent?" One day, I want to, I want to ......" thinking of the bitterness of reading, this thing didn't say cruel words in the end. Seeing that Hou Hu was no longer uncomfortable, everyone no longer cared about him, and continued to ask Jia Qing for advice on arithmetic.

Ruyan said: "Childe is really a great talent, if you follow Childe's method, then not only from one to one hundred, one hundred to one thousand, thousands to ten thousand becomes very simple, and even any continuous number can be added up, you can quickly calculate the answer?" ”

Xie Guowei added: "Indeed, this can be regarded as a great talent, even the math gentlemen in the academy may not know this algorithm!" ”

Jia Qing also realized that at this time, the knowledge of mathematics was too weak and not enough attention was paid to it, and even the calculation could be retained by the Guozijian It was considered lucky, because there was still a household in the court that needed to use counting, otherwise, it was estimated that it would be even more miserable.

Therefore, he decided to popularize some mathematical knowledge with the people around him, even if the effect is small, but it is better than nothing.

"Actually, it's not just continuous numbers, there is such a simple algorithm. Many other numbers with certain rules, their algorithms have a simple way, as long as people summarize them carefully, such as ......"
