Xu Yan was also amused by the boy's behavior, but she didn't show it.

Seeing that the other party was awakened by Lu Zhi's cough, he looked at it in amazement, and the extra weight that was just about to reach his lips was in mid-air.

Immediately thought of something, and hurriedly put down the calculation plan and ran out from behind the table: "Student Zu Heng meets Her Royal Highness, Your Highness Jin An." ”

"The student has seen Mr. Lu, Mr. Lu is good."

"No need to be polite."

Xu Yanjing walked to the table where Zu Heng had just worked, picked up the calculation chip he had just put down and looked at it carefully: "This is your newly developed extra weight calculation chip?" ”

"Huh? Yes. ”

Zu Heng didn't expect Her Royal Highness to come straight to the calculation, but he hurriedly saluted back: "Your Royal Highness, yes, this is the new research of the students. ”

Speaking of this, the young man even left behind the weakness of his heart when he saw the superior, and hurriedly stepped forward to tell her about the use and improvement of this calculation.

"Your Royal Highness, you see, this is to calculate addition and subtraction, and this is to calculate multiplication and division, so that you can calculate the square and the cube."

As he spoke, he moved the calculation chip in his hand and showed her the calculation himself.

Xuyan: "Very good, you have a good idea. ”

Receiving the appreciation of Her Royal Highness, a bright smile bloomed on the young man's raunchy face.

He immediately thanked him again and again and promised: "Thank you Your Highness for your approval, the student union will work harder and carry forward the arithmetic skills." ”

"Well, it's in the right direction."

"It's just that if you add more weight, the data it can calculate is limited." ”

"If you want to have no problems with computing in the future, I hope you can study it more deeply."

"As for your method of using this extra weight, I also hope that you can compile it and form a teaching material to teach more Daqin students."

"Your Highness, don't you think that the ideas and practices of the students are useless?"

Although he was very happy to be praised, Zu Heng remembered the picture of being ridiculed these days, and he was a little nervous, "Everyone says that arithmetic is outdated......"

"Arithmetic is the foundation of all calculations, how can it become obsolete?"

Xu Yan knew that this young man was afraid that he had experienced a lot of ridicule, and immediately cheered him up, "At any time in life, you can't do without arithmetic." ”

"Craftsmen can't make utensils without it, otherwise they can't make beautiful and stable utensils; Officials can't do without it, otherwise they don't know how much food their people will consume every month; The general's march and battle are inseparable from arithmetic, otherwise he does not know how to effectively distribute the military rations and materials he carries; ……”

A series of examples of many industries that are inseparable from arithmetic, covering almost all aspects of daily life.

Zu Heng listened to what Xu Yan listed, and his eyes became brighter and brighter: "So, arithmetic is the foundation of everything going smoothly?" ”

"Yes, arithmetic is the foundation of everything, and it's very important."

"So, I hope you can use more snacks in the calculation methods and tools." ”

"In addition, the extra chips you have newly researched will be brought back to the palace and handed over to your father, and he will be knighted for you."

"Hey, hey, hey...... It doesn't matter if you are knighted or not, the main thing is that students like to study this. ”

Zu Heng smiled very honestly, "However, if the knighthood represents His Highness and His Majesty's recognition of the students, the students are also very happy." ”

"Hahaha......"

Yan Yan was amused by the young man's words.

Although he is a madman who loves scientific research, he is not pedantic.

Know when it's just right to get what you deserve.

After respecting Confucianism alone, everyone in other industries consciously thought that they were inferior to scholars, and Xu Yan preferred the current prosperity of a hundred flowers.
