If we were to use precise words to describe the bunch of playboys in Cuiyun's room, especially Zhang Chen and Lu Sanlang, then the word "complex" could probably barely explain their moods and feelings.
Before, when they were in the hall of Zhang's house, even though Tang Ming and Xie Wanquan accused Zhang Shou of deceiving the world and stealing the reputation, Zhang Chen and Lu Sanlang felt that Zhang Shou's height, shoulder breadth, and the tone and intonation of his voice were completely different from the "old gentleman" who had taught them before.
After that, Ge Yong suddenly showed up again. The two of them were even surprised and delighted to speculate whether they had actually become disciples of this imperial teacher, but that he was just playing a trick on them and had designed such a conversation last night.
But now after going around in circles, no matter who that "old gentleman" was last night, they were kicked to Zhang Shou by Ge Yong anyway!
At this moment, a large group of people, led by Zhang Chen and Lu Sanlang, were sitting obediently in the Qingfeng Xulai Hall, staring at Ge Yong and Zhang Shou, who were sitting opposite each other at a small square table, talking about something they could not understand, as if it were a mathematical problem from a heavenly book.
Ge Yong was talking about the method of dividing a circle and the hypotenuse; Zhang Shou was talking about infinite series and iterative methods... until he got to Arabic numerals, after just a few words, Ge Yong suddenly became so angry that his face turned blue and he stood up abruptly.
"Those weird talismans from the barbarian lands are not worthy of being compared with abacus sticks!"
After hearing this, the young dandies were greatly encouraged.
Could it be that just after he acknowledged his last disciple, the teacher and the student had a falling out in the blink of an eye
In this way, they can take revenge if they have grievances!
However, something they did not expect happened. Ge Yong strode forward, grabbed Zhang Shou's sleeve and dragged him up. Then he ignored these poor guys and walked out.
Lu Sanlang, who boldly turned his head to look, even saw that when Zhu Ying hurriedly ran after him, the old man glared at her angrily.
"Old man, I want to discuss math with this kid. Little Yingying, don't come and join in the fun! As early as when you were seven or eight years old, I discovered that you have no talent for math!"
Seeing Zhu Ying trying to refute him unconvinced, Zhang Shou smiled and said, "It's okay, it's just a small question about numbers."
To be honest, he, who had always lived in the countryside, was surprised and delighted when he first discovered that Arabic numerals, which were only truly popularized in China very late in history, were introduced into all walks of life in the early years of this dynasty under the strong promotion of the court.
Perhaps the ancient Chinese counting method of abacus was very advanced, but it is definitely not a coincidence that Arabic numerals from India could conquer the whole world, even defeating the Latin numerals that once dominated Europe, and finally developed into the most important component of basic mathematics!
But when Arabic numerals were gradually becoming popular throughout the Ming Dynasty, there were still people who insisted on using abacus symbols as a means of calculation. For example, the old man Ge in front of him was a die-hard supporter of abacus. He really didn't expect this.
So, when they left Qingfeng Xulai Hall, he, who was originally dragged by Ge Yong, winked at Qi Liang who followed him out, and asked someone to help Zhu Ying to watch the place, and then he took the old man to Shuibo Buxing Hall. He didn't say anything, but took the paper and pen from the bookshelf, spread it out in front of Ge Yong, picked up the pen and dipped it in ink, and wrote a number casually.
