Ning Yunxi didn't say anything, after all, Teacher Chu did not name her.

The experts asked Principal Peng to preside over the meeting, and Principal Peng generously gave the experts to preside over the scene. The experts said to the teachers: "Teacher Chu, sit down first. Teacher Ning, you and the children sit down together. This time we are here mainly to ask Teacher Ning to introduce new abacus teaching methods to everyone. Teachers in other schools can also put forward opinions and discuss together."

After hearing what the experts said, Teacher Chu did not stop and did not sit down immediately on his own school's point of view: "In the eyes of teachers and students in our school, Teacher Ning's original bead algorithm cannot be distinguished from the three calculation combinations taught to students by our school. Liu Nini had learned the three calculation combinations before in our school. Everyone in our school must learn the three calculation combinations."

The combination of three arithmetics refers to the combination of abacus and oral calculations, but in essence it is not separated from the abacus.

Teacher Chu said this, and the experts who came down to investigate had similar questions as the teachers in the market. After all, almost no one here saw what happened on the scene that day, or there were people present at that time, but at that time, they did not notice the details of the plan of the students of Class 3 of Year 6.

Teacher Zheng suggested to Ning Yunxi: "Teacher Ning, can you let the child do a few questions on the spot for us to see?"

Ning Yunxi didn't want the children to show off their skills, but she couldn't let the children bear the grievances of being questioned, so she nodded.

Six children were elected, three of whom were students who participated in the competition that day, and the other three were selected. The children sat in a row on one side of the table, and opposite were a row of teachers and experts.

Teacher Zheng wore reading glasses and wrote the first question for the children: "May I ask, what is the equivalent of 63 times 85 times divided by three plus one hundred and seven?"

As soon as I opened my mouth, the expert gave a student with a major exam. Think about it carefully, it makes sense. The child facing the experts is said to have won the first and second place in the city's abacus competition. This question is not the highest difficulty.

In front of the six children, paper, pen, and abacus were provided on site.

Everyone soon discovered that when the children heard the topic, they did not start writing, two did not move paper, three did not move abacus. Almost all the children blurted out and shouted, "One thousand eight hundred and ninety-two."

Because the children's answers were a little fast and the voices were inconsistent, the experts and teachers on the scene were a little confused in an instant. However, what was surprising was that the children answered the questions so quickly that almost the experts finished reading the questions and immediately gave the children a synchronous answer.

Teacher Zheng was slightly surprised and discussed with Teacher Deng and changed the way of setting the questions: "You will answer one question by yourself. I will give each of you questions, and you will answer the questions in the order. Please answer the first classmate on my left hand."

Immediately afterwards, six questions were read out from Teacher Zheng, and the difficulty was similar to the first question before. The children still answered the questions quickly, almost synchronized with the experts' questions. Some of them had answered the answers in less than a second, and all the answers were correct.

Let’s see that the children have never moved the pen and abacus in front of them.

this?

Is there a faster calculation speed than abacus without an abacus?

All the teachers on the scene were surprised!
