Chapter 132: Compare Arithmetic with Me?

"Who is this person?" asked Princess Chengxing.

One of her disciples said: "I know this person, I heard that Princess Xingyue recently invited someone into the princess's mansion, it is the immortal Gu Chao in the wine, I think this person is here." ”

Princess Chengxing looked at Gu Chao: "You just come late and want snow, can you drink a cup of nothing?, the pear blossom courtyard dissolves the moon, and the wine in the catkins pond is faintly windy. ”

She praised with a sigh: "Being so young and so talented, it really makes this palace admire." ”

"If you come to my house as a guest, you will be guaranteed to be treated twice as well as being a guest here. "As soon as Princess Chengxing came, she offered twice the price to poach people.

After Gu Chao heard this, he couldn't help sneering, what are you kidding, if you really go to her subordinates, that's the real wandan. Although the doorman can serve everywhere, this one does not do that. But when the two sides are hostile, throw yourself into the other, and the character is questionable.

In today's world, the character is questionable, once this reputation spreads, who dares to matter?

This is very detrimental to their future prospects.

If you really agreed, you are really a fool, greedy for small profits and forget about big profits.

Besides, Gu Chao really looks at Princess Xingyue very pleasing to the eye, although Princess Xingyue pretends to be high every time, she is actually still a somewhat naïve little girl. And this Chengxing princess gives people the feeling that this is not the case at all, I feel that this person's heart should not be too big, and it is a little mean.

Since he intends to bet on Princess Xingyue, he can't be half-hearted, rat-tailed at both ends.

Gu Chao shook his head and refused Princess Chengxing's wooing.

Princess Chengxing saw that Gu Chao rejected her without hesitation, and she was slightly angry in her heart, but she didn't show it on the surface, but she still smiled slightly, which was quite amorous.

Xu Xuan looked at Gu Chao: "Can you do it?"

Princess Xingyue and Kong Xing'er were also a little skeptical.

Gu Chao said lightly: "Okay, can't you? These ten questions should be solved in less than half a pillar of incense." ”

"Nonsense, shameless. Jia Wuyan snorted coldly at the moment: "These ten questions are the ten questions I have drawn from my life's learning, if you can solve them within three days, even if you can solve them within three days, I can't solve them in the three pillars of incense, I am afraid that today only my master and ghost operator can solve them in the three pillars of incense, you actually said half a pillar of incense, it is really shameless." ”

Not only Jia Wuyan, everyone else felt that Gu Chao was blowing nonsense.

Although there are few people who study arithmetic, they all know that arithmetic is a discipline that is difficult to learn and difficult to master.

Seeing so many questioning eyes, Gu Chao sighed: "Bring paper and pen." ”

Pen and paper were brought right away.

"Give me the ink mill. Gu Chao said lazily, sometimes you have to be lazy, you can find someone to grind the ink, why bother grinding the ink yourself, and after a while, you have to start calculating, you have to keep writing, there must really be someone on the side to grind the ink. Kong Xing'er and Xu Xuan, one is a Confucian, the other is a Zongheng family, and naturally they refuse to polish Gu Chao's ink, but Princess Xingyue's Yahuan Caiyun faintly feels that this is the time to make great contributions. Caiyun didn't believe that Gu Chao could solve these ten questions in half a pillar of incense, but when he saw Gu Chao's eyes and posture, it was the same as when he was about to write the poem that Gu Chao gave to Princess Xingyue, and he gave such a look, which seemed to be quite sure. Caiyun is a very ambitious girl who wants to make meritorious contributions, so she stood up: "I'll grind the ink." ”

What a shrewd girl.

At this head, there are a lot of people in the Yahuan profession.

Don't underestimate that.

After Gu Chao finished sighing, he began to calculate the problem.

They said that they couldn't finish it in the time of half a pillar of incense, and Gu Chao preferred to finish it in the time of half a pillar of incense. ...,

Such a topic can't be counted as a half-pillar of incense, which is a strange thing.

If you don't even have such self-confidence, then you really don't need to mess around.

First, the first question, "One day, the student asked the Master how old he was, and the Master replied, "When I was three years old, I was three years old, and when I was three, I was thirty and nine." Ask, how old is the student, how old is the master?"

Gu Chao directly went to x and y, first set the master's age to x, and then set the student's age to y, x-y=y-3, and then x-y=39-x, so this is a binary equation problem, the solution is also super simple, x is equal to twenty-seven years old, y is equal to fifteen years old, Gu Chao brushed down the answer to this question, the master's age is twenty-seven years old, and the student's age is fifteen years old.

Gu Chao calculated a problem by brushing it like this, and it was so fast. Xu Xuan and Kong Xingzi immediately went to the right place, and instead substituted into this question, and found that Gu Chao really solved this problem. However, they can't understand the words used by Gu Chao at all, what x and what y, for them it is similar to ghost drawing symbols, and there are all kinds of symbols, all ghost drawing symbols.

And Jia Wuyan's face changed slightly, he also couldn't understand Gu Chao's ghost drawing, but Gu Chao's answer was right, this should be a coincidence, it may be that he had done a similar question, so Jia Wuyan is quite calm now.

After Gu Chao finished calculating one question, he began to calculate the second question.

The second question is like this: "Nine hundred and ninety-nine dollars, buy one thousand seasonal pear fruits." Eleven pears are nine, seven fruits are four dollars, how much is the price of pear fruits?"

Similarly, assuming that the number of pears is x and the number of fruits is y, then a simple binary equation of 11/9x+4/7y=999, x+y=1000, and finally x is 803 and y is 197.

Brushing and brushing, the answer to the second question came out, the price of pears is 803 wen, and the price of fruits is 197 wen.

In the second question, Gu Chao was drawing a ghost again, Xu Xuan and Kong Xingzi took this answer and checked it in the original question, and it was right, and they couldn't help but be even more surprised. And Jia Wuyan gradually realized that something was wrong, and his complexion changed slightly.

You don't have to do the third question, this Kong Xing'er remembered the answer and came up with the answer.

The fourth question directly said that the master did not know the depth of the well, so he used a rope to measure the well, and the rope was broken three times, and the remaining rope outside the well was three feet;

Gu Chao didn't have to think about it, and directly flew a few ghost drawing talismans that other people couldn't understand at all, and calculated the answer, the well was five feet deep and the rope was twenty-four feet long.

That's right again! After Xu Xuan and Kong Xing'er recalculated, they were really shocked. And Jia Wuyan's face changed greatly, and he muttered in his heart, how could it be possible.

The fifth question, today there are nine embankments, there are nine trees on the embankment, there are nine branches on the wood, there are nine nests on the branches, there are nine birds in the nest, there are nine feathers in the birds, and there are nine forks in the hairs.

This problem is actually quite simple, that is, nine times nine times nine times nine times nine times nine and then multiplied by nine and so on and so on, although this multiplication consumes a little time, but it is also quickly calculated, and the result is 4,782,969.

After the fifth question was made, Xu Xuan and Kong Xing'er had to recalculate again, but the recalculation of this question had far exceeded their level, and they couldn't even do the recalculation with the answer, and they couldn't calculate it even after racking their brains. And Jia Wuyan couldn't help but almost vomit blood, how could it be, this question is quite difficult, nine times nine has been multiplied by nine, Jia Wuyan has made mistakes in his calculations many times, or the ghost operator master has calculated the final accurate answer for himself. Jia Wuyan originally thought that it was impossible for the other party to calculate this question, but Gu Chao calculated it so easily.

"How did you come up with this question?" Jia asked without a word.

"Is this question difficult?" Gu Chao couldn't help but look at Jia Wuyan strangely: "It's easy to calculate, just calculate it." ”

Jia Wuyan almost spit out a mouthful of old blood, this question is actually not difficult, but the amount of calculation is a little large, but Jia Wuyan will make a mistake every time he calculates, and as a result, Gu Chao looks like this is a very simple understatement. ...,

And the atmosphere was unconsciously turning towards Princess Xingyue.

Princess Chengxing also found that the situation was not good.

At the same time, Princess Xingyue smiled slightly, restoring the elegance of the future princess of the prison country, and her good impression of Gu Chao in her heart was even stronger. Gu Chao is really amazingly talented, he can write poetry, he can use swords, and he can do arithmetic.

Caiyun smiled secretly in his heart, it seems that he has made a meritorious contribution this time.

It's just that everyone is surprised that Gu Chao is so young, and at his age, even if he puts all his energy into arithmetic, he can't learn so many things. What's more, he practices and writes poetry, and he can do anything, is it possible that in this world, there is really a powerful person who is born to know?

Xu Xuan and Kong Xing'er were a little puzzled by this.

......

Gu Chao didn't know their incomprehension, and he didn't care about their incomprehension at all.

The sixth question, the bamboo is one zhang high, the end is folded to the ground, go to the original three feet, how high is the bamboo?

The vernacular meaning of this question is that a bamboo is one zhang long, and it is broken from the middle so that the end hits the ground, and the end is three feet away from the root of the bamboo.

Gu Chao was quite simple to do, and casually listed a quadratic equation, and finally came up with a height of four feet five and five.

And Gu Chao made this question, Jia Wuyan's face was even more ugly, this question is a secret trick, he is a secret trick of the ghost operator, he didn't expect this trick to be broken.

Question 7, I don't know the number of things today, the remaining two of the three or three numbers, the remaining three of the five or five numbers, and the remaining two of the seven and seven numbers, ask the geometry of the object?

This question is actually very simple, it is a residual theorem, so simple that it explodes, Gu Chao wrote the final answer quite casually, and he didn't even think about it, the answer was twenty-three.

And Jia Wuyan's face became redder and redder.

The eighth question is quite simple, even if Gu Chaoxuan solves it, Jia Wuyan's face becomes more and more ugly.

The ninth question is quite simple for Gu Chao, and Gu Chao immediately solved it, and the speed was amazingly fast.

The tenth question, there is a lender with a thousand dollars and a monthly interest of thirty. Today, there is a lender with 750 dollars, and he will return it in nine days, and he asks how much interest is there?

(Uh, the third more is delivered, asking for subscription support, asking for a monthly pass.) ）

(The general background of this book is China's Warring States Period, and then this is a fantasy and martial Warring States Period, except for martial arts, other aspects are similar to China's Warring States Period, whether it is poetry, arithmetic, or other aspects.) ）
