In the hall of the Li Mansion, Li Hao sat on a chair in the middle, drank a sip of Coke, and ate a piece of two-color horseshoe cake; Eat a piece of water chestnut cake and take a sip of Coke.

The drinks of the main world, the pastries of the Northern Song Dynasty, in the two worlds, only one person can eat and drink with this combination, and the taste is very good.

The housekeeper Ding Fu reported below: "Young Master, the Reminder Tooth Store has provided more than a dozen shops for rent, and after I screened them, I picked three of them, and waited for the young master to make a final decision." ”

Li Hao instructed Ding Fu to find a new store and choose the address of the first photo studio in the Great Song Dynasty. Ding Fu reported the results to Li Hao early this morning.

"Well," Li Hao asked casually after hearing this, "Let's go and have a look, first look at the one closest to the Treasure Pavilion, if it is suitable, choose there, save trouble." ”

"Okay, young master, I'll prepare the carriage."

Li Hao set off after eating the pastries, surrounded by servants, and went to the prosperous area of Quanzhou City.

After looking at the shop to be rented, Li Hao felt quite satisfied, so he didn't continue to look at it and asked Ding Fu to rent here. This place is very close to the Rare Treasure Pavilion, the difference between the two is only more than eighty meters, since he has arrived here, Li Hao went to the Rare Treasure Pavilion to have a look.

Li Hao sat in the carriage, his eyes slightly closed and seemed to be closing his eyes to recuperate, but in fact, the Force induction spread, and the situation on the road was clearly reflected in his mind. Now his Force has taken a big step forward, and he can now control objects weighing 150 grams, and his control range has been extended to 45 meters. He was sitting in the carriage and knew exactly what was going on in the shops on both sides of the road.

Soon the carriage stopped at the entrance of the Treasure Pavilion, and the shop was still noisy, and the flow of people was very dense. Of course, there are many people who see it, and there are too few people who can afford it.

However, the reputation of the Rare Treasure Pavilion has begun, and it is said that even Hangzhou and Yangzhou have heard of the Rare Treasure Pavilion, and even a rich man in Hangzhou has sent people to buy things.

Li Hao got out of the carriage, and a guy hurriedly came to the door: "Young master, someone has answered your question!" ”

"The question? What topic? ”

"Young Master, you posted the arithmetic problem on the second floor, and you said that the person who can answer it can be the bookkeeper."

"Oh yes, has it taken so long for anyone to figure it out?" Li Hao remembered, he wanted to recruit some high-level bookkeepers, so he posted two ancient arithmetic questions, the difficulty is the level of the arithmetic application questions in the main world elementary school, who knew that it took so long for someone to calculate.

Since someone has figured it out, of course Li Hao wants to see it, and when he saw the person brought by the guy, he was stunned all of a sudden.

The answer to the question was two young girls, two beautiful girls dressed in men's clothes to be exact.

Especially one of them, with a delicate melon seed face and a pair of curved willow eyebrows. Those big black and white eyes are like two springs that are clear and not stained with any impurities. It is often said that the eyes are the windows of the soul, and most people with such eyes have an innocent heart. The skin on her face is as delicate as a baby, white and red, blown out, with bright red and moist cherry lips, it is really an angelic face.

The face is the same as that of the angel, but the figure is a little worse than that of the devil. The bulge on her chest was hidden by the men's scholar's robe, and only two small hills with slight lines could be seen. It's a pity, if you wear women's clothes, it should be more eye-catching.

Even if you wear men's clothes and can't see your figure clearly, just with this face, it is enough to harm the world. Li Hao's computer wallpaper collects a lot of pictures of beautiful celebrities and beautiful models, and compared with the girl in front of him, more than ninety percent of the beauties in the pictures will be overshadowed. And the beauties in those computer wallpapers are also blessed with buffs such as makeup and lighting, and the beauty in front of them is just without makeup, and the difference is even farther.

Li Hao said: "Little girl, mathematics is a bit basic, not bad." Are you interested in coming to Li's Commercial Bank as a bookkeeper? ”

The girl was stunned for a moment, and then her pretty face flushed slightly, "I'm just a little basic?" The two questions you came up with, one is the problem of chickens and rabbits in the same cage in "Sun Tzu's Arithmetic", and the other is the problem of surplus and deficiency in "Nine Chapters of Arithmetic", are they both top-notch arithmetic problems, okay? can solve these two questions, but he is only worthy of being a bookkeeper? ”

This time it was Li Hao's turn to be stunned, "Isn't it, this kind of application problem for elementary school students is also a problem?" Or is it a top-notch puzzle? No, there is no reason why Da Song's math level is so bad. ”

Li Hao's surprise became an out-and-out show-off in the eyes of the girl, in the words of the main world, it was an out-and-out pretence. The girl said angrily, "You...... Megalomaniacs! ”

The smile of the stunning beauty is full of moving charm, and the girl's angry attitude falls in Li Hao's eyes, which is particularly eye-catching.

Li Hao smiled: "What I said is the truth, if this kind of fact makes you think I am arrogant, then I will be arrogant." ”

The girl said angrily: "You are not only arrogant, but also Laipi, but also ......" This girl is obviously deeply influenced by ladylike education, and she really can't scold, and after scolding Laipi, she can't think of other scolding words for a while.

Li Hao smiled and said: "It's okay for me to be regarded as arrogant by you as such a modest person, but where am I lying to me?" I'm telling the truth. Well, let's make a bet. In terms of mathematics, if I answer incorrectly, you can take one of the things in this Treasure Pavilion, how about it? But if I can answer it, what do you do? ”

The people around gasped, the stakes were too big, and some of the goods in the Treasure Pavilion were worth a fortune. The girl was also stunned for a moment, she didn't expect Li Hao to dare to make such a bet, could it be that he really had amazing talent in arithmetic? The girl couldn't take out something of equal value to bet on for a while, after all, there were some things in the Treasure Pavilion, one piece was worth tens of thousands, although she was from a huge rich family, but such an amazing bet would never be able to come up.

Although the girl was confident that she would win, there was no corresponding bet.

Li Hao saw that she didn't speak, and said with a smile: "I think the little lady is also reading, and her calligraphy should be very good." Well, if you lose, you can copy a poem to me as I ask. ”

The onlookers exclaimed in unison, a word can be equivalent to any piece of goods in the Treasure Pavilion? Is there such an expensive word in the world? Not to mention Su Shi, Huang Tingjian, Mi Fu, Cai Jing of this dynasty, even if it is the true hand-me-down of the book saint Wang Xizhi, it is not necessarily so valuable.

When the girl heard this, she agreed without thinking about it, "Okay, then I'll answer the question." ”

Li Hao made a "please" gesture and said, "Go to the store and talk slowly, you can come up with as many questions as you want." Ding Fu, prepare a few pieces of water writing cloth. ”

The two of them entered the Treasure Pavilion and came to the men's lounge, which was not disturbed by any guests, and was suitable for solving math problems.

The girl began to write a few questions on a water writing cloth with clear water. Li Hao took it and couldn't help laughing, the ancient text above was translated:

"Use a rope to measure the depth of the well, fold the rope three times to measure, the remaining 4 meters outside the well, fold the rope four to measure, the remaining 1 meter outside the well, find the depth of the well and the length of the rope."

"100 adults and children eat a total of 100 steamed buns, and it is known that each adult eats 3 and the child eats 1 together. How many adults and children are there? ”

There are several similar questions in a row.

Li Hao shook his head and said with a smile: "Binary equations, can you do something more difficult?" As he spoke, he set up two unknowns x and y on the water writing cloth, and solved the answer.

The girl didn't feel strange that Li Hao could answer it, she was the first to come up with a shallow question. But no matter what the topic, Li Hao used two strange symbols to calculate and get the answer, and used a general method to easily solve this series of arithmetic problems.

The girl froze, this is too unbelievable.

The girl asked another question: "Today there is a chicken Weng, which is worth money; The hen is one, and it is worth three; Three chickens are worth one. Where you buy 100 chickens for 100 dollars, ask the chickens, mothers, and catfishes? In Li Hao's words, this is: "A rooster costs 5 yuan, a hen costs 3 yuan, and a chicken costs 3 yuan, and I bought a hundred chickens for 100 yuan, and asked how many roosters, hens, and chickens are there?" ”

Li Hao smiled: "Oh? The ternary indefinite equation, this answer should not be the only one, okay, I'll get it all for you. ”

After Li Hao solved these answers, the girl couldn't hold back any longer, "What do you mean by these symbols, how can you figure them out so quickly?" ”

"These symbols represent the unknowns in the problem, and by transforming these equations, the unknowns can be calculated."

The girl's eyes widened, "How can this be?" Can all questions be counted like this? ”

"It should be said that this kind of problem can be calculated in this way, even if there are many unknowns. Of course, if there are many unknowns, you can use the matrix operation of line algebra, forget it, you don't understand this. ”

This...... Is this to simplify the complex and get back to basics? This is the road to simplicity, and everything is unchanged? The girl was stunned, the talent of this person in front of her was enough to write books and speak, set up a family of speeches, and spread them to all generations.

This is the realm of a generation of grandmasters who started a sect in mathematics!

The gap between her knowledge and this person is too huge, too far away, so big that she doesn't even know where the gap is, and she doesn't know how big the gap is. It's like looking up at the stars, only knowing how far away, but how far away you can't estimate at all.

The girl had already admired her five bodies, but because of the previous bet, she still held on to the hope of what happened, hoping that Li Hao would not be able to do some remote arithmetic problems.

But the girl soon understood that her thoughts were too naïve. When the level reaches a certain height, the so-called deviation and strange questions are nothing at all.

Li Hao is also a student of a famous university in science and engineering, Huaxia Institute of Technology, which can be ranked among the top five universities in the country. How could he be stumped by such a question of elementary school arithmetic? In fact, it is not all at the elementary school level, and occasionally there are junior high schools, but this makes no difference to Li Hao at all.

The girl stopped writing, no matter how many questions she asked, it was in vain, the person in front of her didn't need to think at all, she got the question and calculated the answer casually, and often answered the question faster than she did.

What surprised her even more was that this man inadvertently uttered a lot of mathematically specific terms. She didn't understand what that meant at all, but she could see that this person's arithmetic method was self-contained, and it did not belong to the routine of the Ten Books of Arithmetic, but opened up a broader world in arithmetic.
