Lu Dongzan began to come up with the question, only to hear his loud voice, and said slowly: "I came up with an arithmetic problem, entitled: The total number of pheasants and rabbits is forty-nine, and there are a hundred legs on the ground, ask how many pheasants and how many rabbits?" ”

Li Hao thought that he was going to come up with a difficult problem, as soon as he heard this question, he almost laughed, this problem is too simple, you can easily calculate the answer with the simplest binary equation, not only that, in his previous life, he had seen this question more than once, and he memorized the answer, and he didn't even have to calculate it.

Li Hao immediately held a pen and wrote the answer on the paper: "Forty-eight pheasants, one rabbit." ”

However, when he looked up after writing the answer, he found that all the ministers on the opposite side were frowning and thinking, it was obvious that they were also calculating this question, and this question seemed to be difficult for them, among these people, the most serious was Li Tai, I saw Li Tai's eyes slightly up, and his lips moved rapidly, as if he was acquiescing.

Although Li Hao didn't have a good impression of Li Tai, he was thinking in his heart when he saw him so serious about calculating problems: "Li Tai is very smart, and he is very talented, proficient in a variety of academics, he should have been able to become a scholar, but unfortunately he was blinded by that dragon chair, and now he is deeply stuck in the mud and can't extricate himself...... It's a pity; Speaking of which, the initiator of all this is Li Shimin, who favors Li Tai too much and breeds Li Tai's confidence in seizing the throne. ”

Thinking of this, he couldn't help but turn his head to look at Li Shimin, only to see that Li Shimin was also frowning and pondering, obviously Lu Dongzan's question was very tempting, and even Li Shimin wanted to give it a try.

Soon, the sand in the hourglass had leaked, and Xu Lian shouted: "Everyone, please stop writing, otherwise you will be judged as a wrong answer." ”

No one was holding a pen at all, because Li Hao had already written the answer, and as for the others, the paper was blank, and no one except Li Hao had calculated the answer.

Li Shimin did not calculate the answer, the officials present did not calculate the answer, this question is too difficult for them, in fact, this is normal, ancient China did not pay attention to academics, only articles, arithmetic was regarded as a sideline in the eyes of people at that time, which also led to China's science and technology in the feudal dynasty has been stagnant, the West is carrying out the industrial revolution, and our country is still kneeling to the emperor and shouting long live my emperor.

Looking at the expressions of the ministers of the Manchu Dynasty looking forward to the answer, Li Hao knew that no one present estimated that no one could calculate the answer, because ancient Chinese arithmetic was not developed, and ordinary people would not delve into arithmetic, and if they wanted to solve this problem, unless the ancient professional arithmetic scholars came to calculate, and even if they were professional arithmetic scholars, it would not be as easy to solve this problem as Li Hao, because the ancient arithmetic in China was relatively redundant and not as concise as the arithmetic of later generations.

Li Hao suddenly sighed, he has been in this world for some years, and has not yet brought this world civilization, perhaps, it is time to popularize the knowledge he brought to the world, so that the world can understand the importance of these academics, so that in the future, even if our nation is not in the prosperous era of the Tang Dynasty, it will not lag behind Western countries, because we have advanced science and technology, at that time, maybe Li Hao is no longer there, but these academics will be passed on from generation to generation, and develop and grow, and finally ...... Become a science.

Just as Li Hao was pondering, Li Tai suddenly said: "Father, the answer this time, Erchen has calculated it, and let Erchen announce the answer." ”

Everyone was shocked when they heard this, they had long heard that Li Tai was proficient in arithmetic, but they didn't expect Li Tai to calculate this problem, and all the ministers couldn't help but secretly praise Li Tai, after all, they didn't calculate the answer.

Li Hao looked at Li Tai, only to see that Li Tai was radiant and quite impressive at the moment, obviously complacent about his cleverness, and at the same time, he could show his hand in front of Li Shimin, one of the big reasons why Li Shimin favored Li Tai was that Li Tai was smart and learned everything faster than others, and Li Tai worked very hard.

Li Shimin said happily when he heard this: "Okay, Qingque has actually figured out the answer, and this time the answer will be announced by you, how many pheasants and rabbits are there?" ”

"Back to my father." Li Tai arched his hand and said, "There are forty-eight pheasants and only one rabbit." ”

"Forty-eight pheasants, one rabbit?" Li Shimin recited silently, and at the same time checked it in his heart, and sure enough, it added up to forty-nine, a total of one hundred feet.

At this time, Lu Dongzan on the side also smiled and said: "King Wei is really smart, Ge Dongzan admires it." ”

Being so praised by the first wise man of Tubo, Li Tai was so happy that his eyes couldn't see, and he hurriedly bowed his hand to Lu Dongzan: "Where, where, it's ridiculous." ”

"Alright." Li Shimin raised his hand and said, "Let's see how many of the contestants answered correctly." ”

Xu Lian had already taken away Li Hao's answer sheet, and then showed the answer sheet and said: "Back to Your Majesty, only the Marquis of Lantian County wrote the answer, and the rest of the contestants did not put pen to paper." After he finished speaking, he turned around and showed Li Hao's answer to everyone, and there was an exclamation in the crowd, and Li Hao also answered correctly.

As soon as he saw that Li Hao also answered correctly, Li Tai was immediately unhappy, and he worked hard to calculate the answer, he thought that he could surpass Li Hao, but he didn't expect Li Hao to answer too, unhappy, very unhappy.

In fact, he is not the only one who is unhappy, the prince Li Chengqian is not happy, why, Li Tai and Li Hao have calculated the answer, Li Chengqian has not calculated it, and these two people are his biggest enemies, in this era, arithmetic is a manifestation of wisdom, surpassed by Li Hao and Li Tai in wisdom, can Li Chengqian be happy, a face is so gloomy that it seems to be covered by dark clouds.

Li Hao answered Lu Dongzan's question correctly, Lu Dongzan was slightly surprised, because he didn't expect Li Hao to know arithmetic, but he was only slightly surprised, in his opinion, no matter how powerful Li Hao's arithmetic is, it is limited, after all, Li Hao is only in his early twenties, he is too young, at most he has only learned arithmetic for ten years, but he is different, he has been studying arithmetic for more than 20 years.

Next, it was Li Hao's turn to ask the question.

Li Hao had already prepared the question, and said slowly: "Since Lu Daxiang has an arithmetic problem, it can be seen that Lu Daxiang is proficient in this way, so I will also make an arithmetic problem, but my question is a bit long, so I wrote it down, in case other contestants have a bad memory and forget it halfway." As he spoke, he handed Xu Lian a piece of paper full of words in his hand.

Xu Lian took the paper and read it aloud: "Lao Wang sells peaches, the purchase price is 450 yuan a catty, he can't sell it, the peaches are going to rot, he sells them at a loss for 300 yuan a catty, someone bought a catty of peaches, give a tael of silver, Lao Wang money change, took this two pieces of silver to find a neighbor for 1000 yuan, came back to find a customer for 700 yuan, and then the neighbor found that a tael of silver was fake, came to find Lao Wang, Lao Wang could only accompany the neighbor to the consistent money, and asked Lao Wang how much money he lost in this business. ”

(Readers can calculate this question together, the answer is written in the comment area, and I will see how many people can answer it correctly.) ）
