When Zhang Shou finished the morning exercises and new content, it was lunch time. He was not a good teacher and was not used to repeating things over and over again, so when he selected students in Jiuzhang Hall, he first used written tests and then interviews to personally test everyone's thinking ability, at least to ensure that his students were not stupid.
However, it was not just the people from Jiuzhang Hall who accompanied the prince to study, there were also Zhang Dakuai and two others from Banshan Hall, and six students from the Imperial Academy. Even if Zhang Dakuai had worked hard to study the arithmetic, it would be a foolish dream to keep up with the progress, let alone the others
So, when the class was over, Zhang Shou saw the boring faces in front of him and smiled nonchalantly: "Every profession has its own specialty, especially mathematics. There are very few people in the world who are truly good at it. You have been ordered to serve the prince to study, and those who have become interested in mathematics are naturally gifted. If you don't understand, don't force yourself."
"Because for ordinary people, it is enough to learn addition, subtraction, multiplication and division, understand account books and keep accounts."
Zhang Dakuai had originally vowed to apply for the Jiuzhang Hall, but after a few classes, he was almost discouraged. When he heard what Zhang Shou said, he saw that no one else said anything, so he couldn't help but ask, "Teacher, since you said that just understanding the basics is enough, then why do you have to teach such difficult things? Your Highness the Crown Prince has learned so many mathematical classics, is it possible that he will have to study in the future?"
Zhang Shou immediately smiled and glanced at the Third Prince who was visibly stunned after hearing this, then he said seriously: "You all know that I don't understand astronomy and astrology, and Teacher Ge's "New Edition of Ge's Mathematics" does not involve such content."
Qi Liang looked a little bit puzzled when Zhang Shou still attributed the New Compilation of Mathematics to Ge Yong, but many other people also understood. Today, many people have already known the real author of "New Compilation of Mathematics by Ge Yong". It was not Ge Yong, but Zhang Shou!
Astronomy and astrology are often mentioned in other mathematical classics, but they are not included in the Ge's New Compilation of Mathematics. This is totally inconsistent with the reputation of Master Ge as a master of astronomy and astrology. However, if this is not Ge Yong's work, but Zhang Shou wrote it under the name of his teacher, then it is very reasonable. Therefore, even though Master Ge has publicly admitted it, there is still not much slander from the outside world.
Since the elder who came from a famous family, had served in several dynasties and was the emperor's teacher had already made it clear, and Zhang Shou had explained it clearly in public, who would think it was too stubborn to hold on to the old master? Aren't they afraid of the emperor's wrath
Therefore, Zhang the big guy continued to play the role of livening up the atmosphere, nodding repeatedly and saying, "I have always wanted to take the entrance exam for Jiuzhang Hall, so I specially went to ask people about the course. I heard that not only is it not in the textbook, but the teachers in Jiuzhang Hall never teach astronomy and astrology."
"So, I just want to break the old idea that mathematics can only be used for astronomy and astrology." Zhang Shou smiled, and then said calmly, "Mathematics is a tool, not just for astronomy and astrology, which are easily linked to prophecies and divinations. Of course, those very complicated calculation formulas and the like, maybe some of you will forget them all within a few years after leaving Jiuzhang Hall."
