Chapter 13: Mathematics

The implication is that others are proficient in poetry and poetry, and they also have their own strengths in piano, chess, calligraphy and painting. Pen Fun Pavilion wWw. biquge。 info couplets are a small way after all, a test of the use of poetry and scriptures, and it is a crooked way to learn it as the main business.

Hou Deyi's words are a little insincere, ordinary couplets may be able to be figured out by time, absolute through the ages, and it is difficult to do it without a deep literary foundation.

Everyone knows this truth, but they prefer to see Su Chengye make a fool of himself. The question is how to make Su Chengye make a fool of himself and ask him to compose poems on the spot? He said to the two eternal absolutes in one breath, and it is not difficult to write a poem, and if he writes an "eternal article" again, it will not be like lifting a stone to shoot himself in the foot.

Su Chengye beat the drum in his heart, really want to let himself write poems? He has a lot of poems in his head, but most of the poems have allusions, and also involve dynasties, personal names, and place names.

In fact, Hou Deyi is also in a dilemma, of course he knows what it absolutely means through the ages, "the axe enters the mountains and forests in time", which can be said by people who don't understand the meaning of poetry and scriptures, and asking Su Chengye to write poetry must be self-inflicted.

The venue was silent, waiting for Hou Deyi to come up with the question.

There was a loud noise in the distance, chirping like a flock of small sparrows. Everyone frowned, the disaster relief meeting is a major event in Sufeng County, and this year's disaster relief meeting is a huge scale and a grand event, what does it look like to be so noisy.

The sound of chirping was getting closer and closer, and the figures gradually became clearer, and everyone's frowning brows relaxed, and some showed their most kind smiles and waved their fat hands to signal someone in the crowd to look here.

"Grandpa" "Daddy"......

With a crisp shout, the "little sparrows" ran over happily.

"Stand up, whoever messes around and goes back will all hit the board. ”

Zhong He called the "little sparrows" back with a clear drink, and the middle-aged and old people in the venue who had already opened their hands were embarrassed, annoyed that Zhong He was "cold-blooded and ruthless", but they didn't dare to show it on their faces.

"It turned out to be Teach Zhong's ......" Shu Ziyu got up and arched his hand, and was interrupted by Zhong He halfway through his words, "This year's disaster relief will invite all the young talents in Sufeng County, and I will take the children to take a look, so that the children can learn from them as an example, I hope it will not disturb everyone." ”

Shu Ziyu, who only said half a sentence, was not embarrassed at all, and nodded with a smile, "It's okay, I had this meaning at first, but I was worried that the child was still too young to discipline and affect the holding of the disaster relief meeting. ”

Su Chengye found Yao Qingqing from the "little sparrow" at a glance, and she couldn't see it, so she stood beside Yao Qingqing and waved her short arms at Su Chengye excitedly.

Zhong He was indifferent on the surface, but he was helpless in his heart. She prefers to read quietly, and the children, who can find role models to learn from them. But Yao Qingqing didn't think so, after seeing his brother's might, he clamored that he must come to the scene, and he really had no choice but to pretend to be a public servant.

"I didn't expect him to have such talent. Zhong He looked at Su Chengye, his eyes showed curiosity, saying that it was for Yao Qingqing's fake public benefit, so he didn't have the idea of satisfying his curiosity.

At the moment when he saw Zhong He, Hou Deyi, who was thinking hard, had an idea, and smiled pretendedly: "I want to ask Zhong Jiaoyu for advice, what kind of homework are taught in the county school?"

Zhong He didn't look at him, and commanded the "little sparrows" to spread out and sit on the ground, and only then did he reply, "The county master manages the school, and he doesn't even know what the county school teaches?"

Hou Deyi was very embarrassed, so he could only hide it with a smile, "If I remember correctly, the county school teaches poetry and scriptures, yin and yang, mathematics, and medicine. Turning to Shu Ziyu, "My lord, in view of Su Chengye's past is really incomprehensible, Xia Guan wants to take the school exam for him in addition to the couplet." ”

Hou Deyi is selfish, of course Shu Ziyu understands this, he hopes that the matter about Su Chengye will end here, and there will be no more turmoil. But because of his initial misunderstanding, Hou Deyi was pushed to the forefront, and the situation was very embarrassing, and it was inconvenient for him to speak out to stop him.

Shu Ziyu chose to acquiesce, not to say yes or disagree.

"Master Xie," Hou Deyi's smile became much more serious, "Su Chengye, I want to test your mathematics." ”

In the county school, poetry and scriptures, yin and yang, mathematics, and medicine are taught, and poetry and righteousness are the most important, and yin and yang, mathematics, and medicine are just some of the most superficial knowledge for them to memorize. Hong Confucian, who is full of poetry and books, has to ask a doctor when he is sick, few people prescribe medicine for themselves, and even less mathematics are involved, just know how to add and subtract, and they will use the rare ones of multiplication and division of the remainder, and they are not account rooms, so they know what to do.

Everyone sighed in their hearts, Lord Hou was too smart and shameless.

"One year, when heavy rains caused the fields to be harvested, there was a wealthy local businessman, and a Xiucai wanted him to donate some money and grain for disaster relief. The merchant was stingy and did not want to donate, and he was worried about being blamed, so he said that I play chess with others, and whoever can win me, I will donate 1,000 taels, and if ten people win me, I will donate 10,000 taels. The rich businessman's chess skills are very famous in the local area, and there are very few who can beat him. ”

"Xiucai said that I will play chess with you alone, no silver, only rice. Put one grain of rice in the first square of the board, two grains of rice in the second square, four grains of rice in the third square, and so on, each square is twice the size of the previous one, and if I win, you take out the rice grains that fill the entire chessboard with 324 squares for disaster relief. ”

Xiucai won, and the rich merchant said that he would keep his promise, and ordered someone to bring a bag of rice on the spot, but in less than twenty squares, one bag of rice was used up, and then the second bag, and then the tenth bag...... The rich merchant found that he could not get enough rice even if he was bankrupt, and his bet had not yet been executed to the thirtieth square. ”

"My question is, how many grains of rice is the rich merchant's bet on?"

Many people have heard the story, but no one has ever seriously calculated it, and the number is too big to make sense.

Zhong He frowned, and reluctantly gave up after silently calculating in his heart for a while, it would take some time to give her a pen and paper and an abacus to calculate on the spot, not to mention mental arithmetic. The more tricky part of this question lies in how Su Chengye proved to everyone that his calculation was not wrong, three hundred and twenty-four grids, except for the first one, the number of rice grains in each grid must be calculated, and the further back the calculation, the more steps are taken, and finally the three hundred and twenty-four numbers have to be added, and the process is extremely complicated.

The level of mathematics here is not high, it is not like a poetic couplet, and it can be distinguished at a glance whether it is indiscriminate or eternal, and whoever dares to mess around will inevitably be laughed at by others. The more complicated the process, the easier it is to be faulted, Su Chengye must not only explain correctly, but also explain it so that everyone understands, otherwise everyone will think that he is wrong.

"I think too much, maybe he is well-read and memorizes poetry couplets, but mathematics is different, mathematics requires accuracy, not heard and seen can be done, must be exercised for a long time, no account room is read to see it. ”

"Why doesn't my brother speak?" asked Yao Qingqing with a small face.

Zhong He touched her head, "I told you not to come, your brother is going to make a fool of himself." Mathematics is often considered the easiest and least necessary to learn, but in fact it is the most difficult, everyone can understand it, but a few can understand it. ”
