Ning Yunxi nodded in agreement with the expert's statement: "So not all children are suitable to practice mental arithmetic to achieve grades. If you have to practice, you can change it to fast mental arithmetic."

"The difference between practicing this mental abacus and abacus is-"

"Developing the right brain with a mental arithmetic is of great benefit to enhancing spatial memory. In terms of mathematical geometry, children need to have their imagination and control over space. We all know that mathematical geometry is the basis of other disciplines such as physics. In practical science, such as engineering designers, etc., it also requires such imagination and computing power."

The other teachers at the scene listened silently, as if Teacher Chu could no longer talk. They only heard Ning Yunxi talk more and more advanced with two domestic education experts. They were not only at the level of primary school mathematics education.

Teacher Zheng, Teacher Deng and Ning Yunxi were having a happy chat. Two flashing wise lights flashed in their eyes: The young math teacher, Mr. Ning, in front of him, has a very good foundation in mathematics, and it is not surprising that he can teach good students.

What is even more valuable is that this young teacher is not proud of his contributions, but has always advocated seeking truth from facts: "The foundation of learning mental arithmetic can be based on the combination of three arithmetics, and learning will be faster."

When Teacher Chu heard Ning Yunxi's words, he immediately smiled and said, "That's right, Liu Nini's grades today will all belong to our school and her alma mater."

Other teachers looked at Teacher Chu: "Teacher Chu, are all students with mental abacus now, except for Liu Nini, your students?"

Teacher Chu: "This - but Liu Nini's answer is the fastest, right? Teacher Ning herself admitted this! If it weren't for Liu Nini's transfer, she would still be a little math genius in our school."

"My daughter never passed the math class while you were in class, how do you explain?"

Where did this completely strange voice come from?

Everyone at the scene turned their heads and saw the woman standing at the door.

"This is--" Teacher Zheng asked.

"Liu Nini's mother." Teacher Fang said.

Lanzhi came to school, and Ning Yunxi was deeply surprised. Because Lanzhi had always been disgusted with the Bayi Children's School, everyone in the courtyard knew about it.

It was said that Lanzhi read the newspapers that said her daughter and Ning Yunxi. It was her biological daughter. It was the same thing as beating and scolding her daughter, but how could someone else bully her daughter? So this morning she thought about it, and it would be better to go to school to ask what the situation was.

After coming, I didn't expect to meet the math teacher who taught Nini before. I dared to say that her daughter was a math genius in the past. Lanzhi's heart was so angry.

"I don't have any knowledge and culture, leaders." Lanzhi said to Teacher Zheng, "But I still see a lot about being a human being. I know what a villain is, a villain who steals other people's grades."

Hearing that the other party seemed to be referring to him, Teacher Chu was surprised: "Who are you?"

"I am the mother of the math genius you mentioned. Don't you know?" Lanzhi said.

Teacher Chu really didn't recognize Lanzhi at once. After all, she was not an excellent student in the previous class or a parent from a special family. It is unlikely that the teacher would remember all the parents of all the students they taught.
