Lu Dongzan started to ask questions, but he heard his voice loudly and said slowly: "I asked an arithmetic question, which was 49 pheasants and rabbits, and there were 100 legs on the ground. How many pheasants are there and how many rabbits are there?"

Li Hao thought he would have to come up with a difficult question, but when he heard this question, he almost laughed. This question is too simple. You can easily calculate the answer with the simplest binary system of equations. Not only that, he had seen this question more than once in his previous life, and he memorized the answers, and he didn't even have to calculate it.

Li Hao immediately wrote the answer on the paper with his pen: "Forty-eight pheasants, one rabbit."

However, when he finished writing the answer, he found that all the ministers on the other side were frowning and thinking. It was obvious that they were also calculating this question, and this question seemed difficult for them. Among these people, Li Tai was the most serious. Li Tai's eyes were slightly rolled up, and his lips were moving quickly, as if he was calculating silently.

Although Li Hao had no good feelings for Li Tai, seeing how he calculated the questions so seriously, he was thinking in his heart: "Li Tai is very smart, talented and proficient in a variety of academics. He should have become a scholar, but unfortunately he was blinded by the dragon throne. Now he is already deeply trapped in mud and cannot extricate himself... It's a pity; speaking of this, the initiator of all this is Li Shimin, who is too fond of Li Tai and has grown Li Tai's confidence in seizing the throne."

Thinking of this, he couldn't help but turn to look at Li Shimin, and saw 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 light, and Xu Lian shouted: "Please stop writing, otherwise it will be said that the answer is wrong."

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

Li Shimin did not calculate the answer, and the officials present did not calculate the answer. This question was too difficult for them. In fact, this was normal. In ancient China, there was no emphasis on academic research, but only articles. Arithmetic was considered a side-minded in people's eyes at that time. This also led to the fact that our country's science and technology had been stalemate in the feudal dynasty. The West was carrying out the industrial revolution, and our country was still kneeling down to the emperor and shouting long live our emperor.

Looking at the ministers in the court looking forward to the answer, Li Hao knew that no one here probably calculated the answer. Because ancient Chinese arithmetic was not developed, most people would not study arithmetic. If you want to solve this problem, unless professional arithmetic scholars in ancient times were used to calculate. Moreover, even professional arithmetic scholars, solving this problem would not be as easy as Li Hao, because ancient Chinese arithmetic was relatively complicated and not as refined and concise as later generations of arithmetic.

Li Hao suddenly felt a lot of emotion. He has been in this world for some time and has not yet brought it to the world civilization. Perhaps it is time to popularize the knowledge he brought to the world and let the world understand the importance of these academics. In this way, even if our nation is not in a prosperous era like the Tang Dynasty, it will not lag behind Western countries. Because we have advanced technology, Li Hao may no longer be there at that time, but these academics will be passed down from generation to generation, and will grow and grow, and finally... become science.

Just as Li Hao was thinking, Li Tai suddenly said: "Father, I have calculated the answer for this time, and Rong Erchen will come and announce the answer."

Everyone was shocked when they heard this. They had long heard that Li Tai was proficient in arithmetic. Unexpectedly, Li Tai actually calculated this question. All the ministers couldn't help but secretly admire Li Tai. After all, they didn't figure out the answer.

Li Hao looked at Li Tai and saw that Li Tai was so energetic that he was quite lustful at this moment. He was obviously complacent for his intelligence. At the same time, he could show off his skills in front of Li Shimin. One of the big reasons why Li Shimin favored Li Tai was that Li Tai was smart and learned faster than others in everything, and Li Tai worked very hard.

Li Shimin said happily after hearing this: "Okay, Qingque has actually calculated the answer. You will announce the answer this time. How many pheasants and how many rabbits are there?"

"Go back to Father," Li Tai bowed, "There are forty-eight pheasants and only one rabbit."

"Forty-eight pheasants, one rabbit?" Li Shimin thought silently, and at the same time verified it in his mind. Sure enough, the total was forty-nine, with a total of one hundred legs.

At this time, Lu Dongzan, who was standing beside him, also smiled and said, "The King of Wei is indeed extremely intelligent, and Geerdong admires him."

Li Tai was so happy that he couldn't even see his eyes when he was praised by the most wise Tubo. He hurriedly bowed to Lu Dongzan: "Where is it, it's a big mistake."

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

Xu Lian had already taken away Li Hao's answer sheet, and then showed it out, saying, "When you go back to your Majesty, only the Marquis of Lantian County wrote the answer, and the other participants did not finish the writing." After he said that, he turned around and showed Li Hao's answer to everyone. There was a burst of surprise in the crowd, and Li Hao also answered correctly.

When Li Hao saw that Li Hao had the correct answer, Li Tai was immediately unhappy. He had tried his best to calculate the answer. He thought he could surpass Li Hao, but he didn't expect that Li Hao would answer it too. He was unhappy and very unhappy.

In fact, he is not the only one who is unhappy, and the Crown Prince Li Chengqian is not happy either. Why did Li Tai and Li Hao calculate the answer? Li Chengqian didn't calculate it. Moreover, these two are his biggest enemies. In this era, arithmetic is a manifestation of wisdom. In terms of wisdom, Li Hao and Li Tai can be happy. His face is as gloomy as if it is covered by a dark cloud.

Li Hao answered Lu Dongzan's question correctly, and Lu Dongzan was slightly surprised because he didn't expect that Li Hao actually knew 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 and is too young. At most, he has only been learning 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 set the question.

Li Hao had already prepared the question and said slowly: "Since Lu Daxiang has a math problem, it can be seen that Lu Daxiang is proficient in this method, then I will also give an arithmetic problem. However, my question is a bit long, so I wrote it down to prevent other contestants from having a bad memory and forgetting it in the middle of the journey." He said, and handed Xu Lian a piece of paper full of words in his hand.

Xu Lian took the paper and read loudly: "Lao Wang sells peaches, and the purchase price is 450 yuan per catty. It cannot be sold. The peaches are going to rot and sell them at a loss of 300 yuan per catty. Someone bought a pound of peaches and gave one tael of silver. Lao Wang made change. He took this tael of silver and exchanged them for 1,000 yuan with the neighbor. When he came back, he found that one tael of silver was fake and came to find Lao Wang. Lao Wang could only accompany his neighbor for money again and asked Lao Wang how much money he lost in this business."
