Since Cai Yong has the heart to ask himself, he must have the courage to meet the challenge, Li Yi said with a smile: "The seniors ask their own questions, and the juniors can give it a try!" ”

This tone is really enough, Cai Yong nodded, and deepened in his heart, he was going to give Li Yi a setback, he still said with a smile on his face: "Qinggang Xian nephew, the old man will ask the question immediately, you can listen well." Pen, fun, pavilion www.biquge.info there are pheasants and rabbits in the same cage today, there are thirty-five heads on the top, and ninety-four feet on the bottom. ”

When Li Yi was a child, he once heard his grandfather say a mantra: multiply the total amount by the high price, subtract the original full number, and reduce the low price at the high price, except for the cheap thing. Li Yi had a hint of a smile on the corner of his mouth, according to this mantra, four times thirty-five, minus ninety-four, and then divided by four minus two. Cai Yong just finished reading the question, "Twenty-three pheasants!" Li Yi blurted out.

Cai Yong was shocked to give the answer so quickly, but he nodded quietly, praising Li Yi for his youth, flexible mind, and fast reaction speed!

However, Cai Yong aimed at the next question, increasing the difficulty by a cut, and reading out the question with a smile on the corner of his mouth: "Today there is a pond square zhang, the center of the leaf is deep, and the water is one foot out. ”

Li Yi was afraid that he would make a mistake, so he had already put the chess book aside and listened to the question with full attention. Who knew that Cai Yong read quickly, and he didn't give him a chance to think at all, and when Cai Yong finished reading the question, Li Yi was stunned and stupid.

It's hard to stop it! Young people, you should stop talking in moderation, and you can't talk so full, there is no room for manoeuvre.

Cai Yong looked at Li Yi with ill will, waiting for him to bow his head and admit his mistakes, so he could naturally preach.

It's no wonder that Li Yi, the three of them have their own strengths, and they must be responsible for the division of labor and give full play to their strengths, so that in the shortest possible time, Jianping will become a thriving and prosperous scene.

If each is short, the house will fall, the road will collapse, the rice will be cooked, and the enemy will be defeated...... Nothing will be accomplished, and it will be difficult to move an inch.

At first, the source also vowed to learn ancient Chinese well, but later whenever a proclamation, regulations, and decrees were issued, Zhang Ying, who wrote a beautiful and talented soft pen, was naturally responsible, and Li Yi didn't have to worry about it. Sailing against the current, if you don't advance, you will retreat. Over time, Li Yi's level of ancient writing not only did not improve, but regressed. This is the reason why he is confused and confused.

Li Yi was extremely embarrassed, and when his true form was revealed, the great savior Zhang Ying arrived, she had already discovered Li Yi's abnormal behavior, but knowing a husband is like a wife, this difficult ancient text, Li Yi had a headache at a glance, and it was normal for him to retreat.

However, to Zhang Ying's surprise, Li Yi did not go out of the book house, but held the book and loved it, and after her head turned sharply, she finally understood that Li Yi must have found the book he liked. That's fine, otherwise Li Yi and Yu Bing will leave under the pretext of leaving for some reason, wouldn't the old man be very disappointed?

Zhang Ying is imagining out of thin air, but Cai Yong knows the layout of the bookstore, seeing Li Yi hiding in a corner, looking through his miscellaneous studies, few people are involved in these side doors, but Li Yi is relishing, can't put it down, and it is strange not to arouse Cai Yong's curiosity.

When he heard Li Yi's restrained arrogant words, Zhang Ying knew that an exam was inevitable, and he was afraid that Li Yi would make a fool of himself, so he couldn't help but slowly lean over.

Sure enough, Li Yi was stuck, Zhang Ying was angry and funny, but husband and wife are one, and they must not look at jokes, she smiled and said: "The Jia in the question is what we often say about reeds." The meaning of this question is: There is a square pool with a side length of one zhang, and in the middle of the pool there is a reed, and the reed is one foot above the water. How long are reeds? ”

The difficulty of this question is all in the difficulty of understanding the meaning of the question, with Zhang Ying's explanation, Li Yiluo's thinking suddenly became clear, he smiled slightly: "This question is very easy, the reed is a hypotenuse, the reed minus one foot is a right-angled side, and the other right-angled side must be five feet, five-five-twenty-five, exactly the sum of thirteen and twelve, and the long is undoubtedly the hypotenuse, that is, the reed is thirteen feet long." The rest is a right-angled side, that is, twelve feet deep. ”

Before Zhang Ying finished reading the question, Li Yi knew that he couldn't escape the scope of the Pythagorean theorem, and this problem was obviously a special case, and in a flash in his mind, he thought of splitting twenty-five into twelve and thirteen, and almost didn't need to calculate, and gave the result!

While Zhang Ying was explaining the question, her mind was also thinking, and as soon as she thought of using the Pythagorean theorem to solve it, Li Yi announced the answer. Zhang Ying couldn't help but sigh secretly, the gap between the two was as big as the sun and the moon. Zhang Ying couldn't help but blurt out praise: "My brother's thinking is no less than in the past, Zhang Ying can only bow down!" ”

Not only did Zhang Ying retreat despite the difficulty, but Cai Yong was also convinced. He is older, and his numeracy skills are not as good as before. But Cai Yong knew that even if he was twenty years younger, he would not be able to reach Li Yi's speed.

However, Cai Yong is still a little unwilling, he must regain face. I flipped through the books, found a problem habitually, and read out the title with a smile: "Today, there are five common wells, and the first and second are insufficient, such as B and one well; B three is insufficient, such as C and one line; Deficiency of propylene four, such as Ding Yifang; Ding Wufang is insufficient, such as Wu Yifang; Insufficient pendulum, such as a garnish. If each has less than a penny, they will be caught. Q: What is the depth of the well and the length of the well?"

Li Yi frowned, and scolded secretly in his heart: What a mess, it's just a lot of. Li Yi couldn't figure it out at all, he looked at Zhang Ying helplessly.

is also thanks to Zhang Ying's excellent memory, and she can imprint such a long topic in her heart word for word. Zhang Yingwan smiled, didn't talk nonsense, and directly translated it into the vernacular: "Five families share a well, A uses a rope to measure the depth of the well, twice the length of the rope is not enough, and the missing share is exactly equal to the length of B's rope; Three times the rope of the second family is not enough, and what is lacking is the length of the rope of C; It is not enough for C's rope to be four times, but what is lacking is the length of D's rope; Five times the length of D's rope is not enough, but what is lacking is the length of E's rope; Six times the length of the rope of E is not enough, but the length of the rope of A is missing; Q: What is the name of the well deep rope? ”

This question is really enough, Li Yi listened to the question and secretly thought about it, trying to find out the trick as much as possible. But Zhang Ying's voice landed, Li Yi was still nowhere to be found, he shook his head, he can't waste time, maybe he is not a special case to this problem, or use a stupid way to solve the application problem by listing equations!

Zhang Ying also frowned on the side, and she secretly complained in her heart: What a mess! Going around, even if you list the equations, you don't know how long it will take to solve them. Zhang Ying gave up directly, she set her eyes on Li Yi, waiting for him to give the result.

In the end, it is a science student, Li Yi thought about it for a while, and a few calculations jumped on the paper. Afraid that Cai Yong saw the flaw, Li Yi did not set an unknown number, but directly applied A, B, C, D, and E, only a moment, Li Yi brushed a little bit to find out the result, he smiled proudly, and announced the answer: "The depth of the well is a multiple of seven hundred and twenty-one, and the ropes of A, B, C, D, and E are multiples of two hundred and sixty-five, one hundred and ninety-one, one hundred and forty-eight, one hundred and twenty-seven, and seventy-six respectively."
