"Fellow civil servants, although arithmetic is not included in the imperial examination, it is often used in daily life. Now I will tell you about my arithmetic method."

Lin Feng looked at the door panel placed in the corner, then at Zuo Peng and Liu Shuo, who were bruised and swollen. Seeing that they were dodging, he smiled and walked towards them.

"Please do me a favor, gentlemen. If you see that there is no door panel in the corner, help me carry it to the lecturer's desk. Thank you!"

With Zuo Peng and Liu Shuo looking so dignified now, how dare they come out to meet people! However, Dr. Zheng Tian also ordered all the officials of Jinshi Pavilion to be present. They had no choice but to come here. Now Lin Feng asked them to move the door panels. It was obvious that he wanted them to make a fool of themselves in public!

Deliberately, this was definitely intentional. This guy Lin Feng clearly wanted to avenge his personal revenge. He had no choice but to go because they had become the focus of attention of all the scholars in the Jinshi Pavilion.

You guys, if you dare to fight with me, let's see how I deal with you.

Zuo Peng and Liu Shuo had no choice but to get up and carry the door panel to the lecturer's desk together, "Marquis Jiangling, where should I put this door panel?"

Lin Feng smiled and said, "No need to let go, just keep lifting it like this."

"Marquis Jiangling, don't go too far!"

"Jiang Linghou, you are avenging a private vendetta."

Zuo Peng and Liu Shuo's expressions of gritted teeth when talking to each other, coupled with the bruised and swollen face, were really hard to look at.

"Haha! Whatever you think. Sirs, please raise the door panel a little higher."

At this point, Zuo Peng and Liu Shuo had no other choice but to follow their words and lift the door panel high. Lin Feng posted the paper prepared in advance on the door panel.

"Everyone, please see, these are Arabic numerals: 0123...9, which correspond to: zero, one, two, three...nine, ten corresponds to 10, eleven corresponds to 11, twelve corresponds to 12, and so on."

"If nine thousand five hundred and twenty seven are written in Arabic numerals, it becomes 520. Do you think this writing method is much simpler?"

As soon as Lin Feng said these words, the eyes of all the scholars in the Jinshi Pavilion suddenly lit up, even Zuo Peng and Liu Shuo who were carrying the door panel were no exception.

This method of Arabic notation is indeed quite simple. Why didn’t I think of it before?

This is the voice of all the scholars in Jinshi Pavilion, including Yue Zhong, Zheng Tian and Huangfu Yunduo.

"For example, what is the total of one thousand 630 four plus five thousand 780 nine? If we use our previous method to calculate this, it will be very difficult. If we use Arabic numerals to calculate, it will become very simple. Please take a look .”

After Lin Feng finished speaking, he picked up the writing brush and calculated on the paper on the door panel in front of everyone. He came up with the answer in a short while.

"Everyone, this is my method of arithmetic, which is simple and clear. If you also find this kind of Arabic numerals useful, you might as well help me promote it. Thank you all."

"Next, if you gentlemen here have any arithmetic problems, please feel free to ask, and I will try my best to answer them."

After Lin Feng finished speaking, a scholar sitting at the front immediately stood up and bowed his hands respectfully, "Jiangling Marquis, Zheng Bowen would like to ask, can all arithmetic problems be solved through this kind of Arabic numerals? "

Zheng Bowen, the son of Zheng Ming, the Minister of Rites, was the number one student in the Imperial Academy and a popular candidate for the top prize in the current imperial examination.

Three years ago, Zheng Bowen successfully passed the Fengyang Prefecture Township Examination with the score of Fengyang Prefecture Jieyuan. For unknown reasons, he did not sign up for the next examination.

Three years later, the year of the imperial examination came again, and Zheng Bowen naturally became the greatest hope of the Imperial College.

Lin Feng nodded, "That's right! Please tell Zheng Shizi your question, and I can answer it for you on the spot."

Zheng Bowen cupped his hand again, "Thank you, Marquis Jiangling, I would like to know how to use these Arabic numerals to quickly calculate what five times one thousand, six hundred and thirty-four is."

In the eyes of the literati of Dayan, arithmetic is just a businessman's lane. As for the top student in the Imperial Academy, he even has to ask Lin Feng for math problems that a primary school student can understand. There is no way this is the reality of Dayan.

"Master Zheng, please take a look."

Lin Feng picked up the brush and started calculating on the door panel, and soon he figured out the answer.

"This...how is this possible?"

The number on the door panel was exactly the same as the one he had worked so hard to calculate. Zheng Bowen was shocked. All the scholars in Jinshi Pavilion, including Yue Zhong and Zheng Tian, ​​were amazed by Lin Feng's fast algorithm.

"May I ask Marquis Jiangling, what is your algorithm?"

Zheng Bowen was very excited, and everyone in Jinshi Pavilion looked at Lin Feng.

Lin Feng smiled and pasted the multiplication table he had prepared earlier on the door panel, "Everyone, please see, this is the multiplication table. As long as you master it, you can answer this question as quickly as I can." Arithmetic problem."

Then, Lin Feng explained the specific usage of the multiplication table in detail based on the question just now. Everyone in Jinshi Pavilion listened very carefully. After the explanation, everyone realized the value of the multiplication table. .

The Marquis of Jiangling is indeed a sage of his time, and arithmetic is truly unfathomable. This is what everyone in the Jinshi Pavilion is thinking at this moment.

If Lin Feng knew what they were thinking at this time, he didn't know what he would think.

Lin Feng glanced at him and saw that all the scholars in Jinshi Pavilion were looking at him with respect.

Why! I don’t want to show off, but my strength doesn’t allow it!

Next, Lin Feng answered several questions raised by the scholars. Time passed little by little, and Lin Feng and Huangfu Yunduo left the Imperial College together in the evening.

After getting along with each other for a whole day, Huangfu Yunduo also had a general understanding of Huangfu Yunduo's personality. Jingjing, well-behaved and sensible was a very good girl. Compared with her, Huangfu Yunyun was as good as heaven and earth. Lin Feng really couldn't figure it out. , how can there be such a big gap between the two of them as princesses!

Huangfu Yunduo was very happy today, and the smile on his face never stopped.

Why! How great it would be if I could stay with Lin Feng every day! It's a pity that he and cousin Tianhu are already engaged. They will get married next year when cousin Tianhu comes of age. Thinking of this, Huangfu Yunduo feels a little disappointed.

"Marquis Jiangling, when will you come to the Imperial College to give lectures next time?"

Lin Feng shook his head, "I may not come to the Imperial College again in the future."

"Why? I remember that at the Queen's canonization ceremony, didn't you promise my father that you would go to the Imperial College to give lectures one day every month?"

"Well... Your Highness, I have told you everything I know. There is really nothing more to say. To be honest, I don't plan to go to not only the Imperial College, but also the General's Mansion in the future."

"How could it be? Didn't you speak very well today? Even the doctors praised you, and the scholars in the Imperial College also respected you."

Lin Feng smiled. He knew his situation well. He didn't want to explain any more, and then he cupped his hands and said, "Your Highness, it's getting late and I should go home. Goodbye!"

Watching the carriage gradually disappearing, Huangfu Yunduo's mood was very complicated.

Qianqian, the personal maid who had been following Huangfu Yunduo, had already seen her princess's thoughts about Lin Feng, and couldn't help but said: "Princess, are you in love with the Marquis of Jiangling?"

Being told what was on his mind, Huangfu Yunduo's face turned red, "Qianqian, do you think there is still a possibility between me and the Marquis of Jiangling?"

"Princess, don't be stupid. Marquis Jiangling has already married Princess Qiuyue, and you have an engagement with Crown Prince Cheng. Unless His Majesty cancels the marriage, there will be no possibility between you and Marquis Jiangling."

"Hey……"

Huangfu Yunduo let out a long sigh, "Qianqian, let's go back to the palace!"

"Yes, princess!"
