Datang: Acting as a celestial mystery at the beginning

Think about it, even if it comes out?

how can that be!

But Li Wenkang saw with his own eyes that Wanshun didn't even have a calculation process, so he came to the result, and even pointed out his mistakes.

Li Wenkang began to doubt his life, could he not be as good as a little girl?After learning so many years of spells, I feel that I have learned them all in vain.

Those other people all stared wide-eyed, and Li Wenkang admitted that he was wrong, and the little girl really counted it right!

"I have another question, little sister, can you answer it?"

Li Wenkang refused to admit defeat, and asked: "Today there are objects whose numbers are unknown. When counting three or three, there are two left, when counting five or five, there are three left, and if counting seven or seven, there are two left. How many things are there?"

"23!"

Wanshun almost blurted out.

Li Yi'an explained this to them, and it came from Confucius' calculation of the scriptures.

"If I want to go to West Market to buy pens, the high-quality pens cost five yuan each, and the low-quality pens cost two yuan. I spent a total of 120 yuan. If I paid [-] yuan, how many high-quality pens and how many low-quality pens did I buy?"

"Ten high-quality pens and twenty low-quality pens."

Wanshun briefly thought about this question for a while and came up with an answer.

My husband said that a problem like this is the evolution of a chicken and a rabbit in the same cage, and the reason is the same.

Li Wenkang's eyes widened in surprise. This question is not difficult, and he can calculate it, but he can't do the process without calculation. He can get the result after thinking about it.

How powerful is this to come up with an answer?

Li Yi'an was also surprised, never thought that Xiao Wanshun's math talent is so high.

Compared with Wanshun, those math geniuses in later generations are almost the same.

"Brother-in-law, am I right?"

Wan Shun raised her head and looked at Li Yi'an as if asking for credit, her big eyes were full of joy.

"Yes, yes!"

"Little sister, I'm sorry, I was blind and arrogant just now, I'm sorry!"

Li Wenkang bowed, full of courtesy, and said first: "I have one more request, I... can I worship you as my teacher?"

His attitude is very sincere, his eyes are getting hotter and hotter, and he wants to learn the method that can calculate the result after thinking about it.

As soon as these words came out, those people who laughed at Wanshun just now felt that they were the joke.

"Brother-in-law!"

Wanshun didn't know how to deal with this situation, so she tugged at Li Yi'an's sleeve nervously.

"If you want to worship my family Wanshun as your teacher, it depends on whether you have the qualifications."

Li Yi'an said: "I taught Wanshun's spells. Now I will give you a question. If you can figure it out before today's poetry meeting ends, maybe I can give you this chance."

"Today, there is a rooster that costs five, a hen that costs three, and three chicks that cost one. If you buy a hundred chickens for a hundred dollars, ask the rooster how much is the hen and chicks?"

Li Wenkang hurriedly took paper and pen to copy down this question, and then fell into deep thought, but he couldn't think of anything. He was about to ask Li Yi'an and the others, but when he looked up, he realized that he had already gone far away.

"Brother Wenkang, I heard that the prince is here too, why don't you go ask the prince for advice."

A man next to him saw that he couldn't figure it out, so he suggested.

"The prince is here too?"

Li Wenkang picked up a pen and paper, asked where the person was, and ran over in a hurry.

Wang Gong, whose full name is Wang Xiaotong, was a famous mathematician in the early Tang Dynasty. He was the first mathematician in the world to propose the cubic equation and its solution.

At this time, Wang Xiaotong was explaining algebra to a group of scholars. As one of the six arts of a gentleman, there were quite a few people who learned it. People like Li Liangping were also among them, and they seemed to be listening to the lecture with an open mind.

Although Li Liangping really wanted to trouble Li Yi'an again, but he lost face just now and made him faceless, and it was not good for him to go again without any reason, so he followed Wang Xiaotong to gain his reputation first. .

"My lord, I finally found you!"

Li Wenkang trotted over, very excited.

"Brother Wenkang, aren't you going to help those students solve arithmetic and math problems? You are in such a hurry and disturbed the prince!"

Li Liangping spoke first.

"I shouldn't disturb the prince, but I have a problem here. I want to ask the prince to look at it, but I can't solve it!"

Li Wenkang quickly handed the paper to Wang Xiaotong.

"This……"

Wang Xiaotong just finished reading the question, thought for a while, his hands trembled slightly: "Where did you come from for this question?"

Chapter 166 The Wang Family's Hint

"Brother-in-law, it's them who bullied me outside the door that day!"

Xiao Wanshun's mood quickly recovered, she held Li Yi'an's hand and danced, and suddenly saw two familiar people, it was Li Yifu and Gao Zhizhou, and there was a group of poor scholars beside them.

"gentlemen!"

When Wanshun discovered them, she was also discovered by them.

Li Yifu ran over excitedly: "Sir, we meet again."

"Brother Yifu, this gentleman... who is it?"

Some other humble scholars asked curiously.

"a friend!"

Gao Zhizhou knew that he couldn't reveal Li Yi'an's identity, and said with a smile: "Sir, last time we took the liberty to interrupt and scare my little sister, it was our fault, so I apologize here, but I knew that sir would also participate in the Chang'an Poetry Fair .”

Wan Shun held Li Yi'an's hand nervously, looking at them with big eyes curiously.

"You come here so free, don't you need to prepare for the imperial examination?"

Li Yi'an calculated the time, and there was only half a month left before the autumn imperial examination.
