Chapter 792 0794 I feel ashamed
Su Li's words were neither exaggerating nor bragging.In the mathematics of this era, what is the three-point four-point is already a very profound theory, but in modern mathematics, it is a super simple problem that elementary school students can calculate the result by simply listing a formula.

For a modern mathematics student to solve the mathematical problems of this dynasty, it is simply a dimensionality reduction attack, which is as difficult as a college student beating a kindergarten child.

Su Li can guarantee that if the students here accept her knowledge of modern mathematics, then looking back at mathematics, it will be as simple as one.

But what Su Li knows well, the people here may not know. Even a well-informed person like Dean Gu fell into hesitation.

On the one hand, he felt that according to Su Li's talent, she would not speak big words; but on the other hand, he didn't understand what was going on with the same number of math textbooks these days.

It is human nature to always have doubts and fears about the unknown.

Su Li knew this, so she was very clear and patient, and said: "Dean Gu, in fact, this mathematics looks difficult, but it is not difficult to learn it in real life. If Dean Gu is interested, I can teach it to you." Dean Gu has some basic knowledge of mathematics, how about letting Dean Gu experience the magic of mathematics for himself?"

Dean Gu is a person with a strong thirst for knowledge. He was very interested in the "Mathematics" textbook that he couldn't understand in the book that day, so Su Li asked Ling Dang to get a pen and paper, and taught Dean Gu the introductory knowledge in person, just like teaching Xiao Zetian's recognition of numbers is the same as addition, subtraction, multiplication and division.

Dean Gu is worthy of being the top smart person in the current era, with a strong learning ability, and he quickly learned about Arabic numerals and how to count with them.

Afterwards, Su Li demonstrated to him the simplest four arithmetic operations of addition, subtraction and multiplication, as well as basic mathematical knowledge such as column and vertical formulas.

In the process of learning, Dean Gu's expression gradually became more and more dignified, because he found that although Su Li's mathematics did not recognize those ghostly symbols and Arabic numerals and various operation symbols at the beginning, once he got started, he became familiar with it. , the following things become more and more miraculous.

No need for an abacus, or even extremely strong mental arithmetic ability, you can calculate the results of various additions, subtractions, and multipliers according to a vertical formula, which is accurate and fast. Compared with traditional arithmetic, which relies heavily on mental arithmetic and abacus, it is simply a heaven and an underground.

Although traditional mathematics relies heavily on the abacus, it cannot be used in the imperial examination examination for mathematics, so it relies on a strong mental calculation and memory ability.But not every student is so strong in mental arithmetic, so many students with weak mental arithmetic ability will suffer a lot in the imperial examination.

But Su Li's vertical formula doesn't require a strong mental arithmetic ability at all. As long as he masters the basic method, even a five-year-old child can calculate it, which is simply amazing!
Su Li only explained the basics to Dean Gu, so he stopped talking. Firstly, time was limited, and secondly, Dean Gu had to digest new knowledge.

Su Li closed the mathematics book and said, "Dean Gu, what you have learned today is just the tip of the iceberg of mathematics. The subject of mathematics is like a vast ocean, boundless and boundless. If you study well, you can solve many things."

Dean Gu was still immersed in the magical mathematics, and he couldn't get his head around it. After a long time, he stroked his beard, stood up with a sincere face, bowed his hands to Su Li respectfully, and said, "Master Su, your mathematics is really good. Even better than the old man in arithmetic, the old man is ashamed and willing to bow down."
