Red Mansion: I relied on the AFK system to create a dynasty

Student F: “What’s the use of this?”

Cen Mingche: "Very useful! Set theory can be used to solve practical problems. For example, the concepts of set theory are used in fields such as probability, statistics, and computer science. Moreover, it can also cultivate our logical thinking and problem-solving abilities."

Cen Mingche's set theory course aroused students' interest.They began to explore the mysteries of sets and learned to use symbols and formulas to express the relationships between sets.Cen Mingche also encouraged them to find examples of collections in their daily lives, which made learning more interesting and practical.

A few months later, the school held a mathematics competition that included questions on set theory.Cen Mingche's students performed well in the competition and achieved excellent results, which made them more convinced of the importance of set theory.

One day, student G walked into Cen Mingche's office excitedly.

Student G: "Teacher Cen, I found an interesting collection that includes everyone who likes mathematics!"

Cen Mingche smiled: "That's a great collection, student G. Mathematics is a beautiful art that can connect people and let us explore the world of knowledge together."

Cen Mingche continues his efforts to introduce more practical applications into his classroom.One fine afternoon in his high school math class, a student asked a question.

Student H: "Teacher Cen, I have been thinking, besides solving problems, are there any other uses for mathematics?"

Cen Mingche responded with a smile: "Absolutely, mathematics is a tool that can help us better understand the world. For example, it is widely used in finance, medicine, engineering and other fields. Moreover, mathematics can also be used to predict In the future, explain natural phenomena and even improve society."

Student i: “Can you give us an example?”

Cen Mingche: "Of course, in medicine, for example, mathematics can be used to build mathematical models to help doctors better understand how diseases spread and formulate effective prevention and control measures. In the field of environmental protection, mathematics can help us analyze climate data, Predict natural disasters so that measures can be taken to reduce their impact."

Student J: “So math is so awesome!”

Cen Mingche: "Yes, mathematics is a powerful tool that can solve various complex problems in the world. I hope you will not only learn mathematics, but also learn how to apply it to real life and use it to improve self and society."

As time went on, Cen’s classes became more diverse and students became more engaged.They began to combine the knowledge of mathematics with other subjects and explore interdisciplinary research projects, such as mathematics and biology, mathematics and sociology, etc.This makes their learning experience more colorful.

One day, the school held a student scientific research exhibition. Cen Mingche's students showed their research results, which attracted the attention of many people.School leaders and education experts came to visit one after another, and they were moved by the innovation and enthusiasm of these students.

An education expert said to Cen Mingche: "Your education method is very unique and can inspire students' enthusiasm and creativity. We hope to promote this method in more schools and benefit more students."

Cen Mingche smiled and nodded: "Education is a force that changes the world. I am willing to share my experience and help more students embrace mathematics and knowledge."

Cen Mingche's educational methods led the students forward, and he next decided to teach them the enumeration method, an important tool for organizing data and information.

Cen Mingche: "Students, what we are going to discuss today is the enumeration method. It is a method of arranging information and data in an orderly manner, which can help us better analyze and understand complex problems."

Student K: “How does the enumeration method work?”

Cen Mingche: "It's very simple, just arrange the information in a certain order or rule. For example, if we want to list all three-digit even numbers, we can start from 100 and add 2 each time until 998. In this way, we Got an ordered list."

Student L: “This sounds like an organizational method for mathematics. But does it have any practical use?”

Cen Mingche: "Of course it is useful! The enumeration method is widely used in statistics, computer science, market research and other fields. It can help us collect and organize a large amount of information and discover patterns and trends."

Cen Mingche demonstrated some examples of the enumeration method, allowing students to gradually understand its practical application.Then, he gave the students an exercise question on the enumeration method.

Student m: "Teacher Cen, I have encountered difficulties with the practice questions. Are there any techniques that can help us complete the enumeration method faster?"

Cen Mingche: "Of course, student M. Sometimes, we can find patterns to avoid listing them one by one. For example, if we want to list all square numbers less than 100, we can notice that they are 1, 4, 9, 16 , 25... These are perfect square numbers. We can enumerate their square roots and get the sequence of 2, 3, 4, 5... In this way, we do not need to enumerate them one by one. "

Student n: “Wow, that’s really smart!”

Cen Mingche: "Mathematics is a subject full of wisdom and creativity, and the enumeration method is only part of it. Learning it can help us better understand the world and solve problems."

In the following courses, Cen Mingche continued to explore practical applications of mathematics.He takes students into the field of data analysis and teaches them how to use mathematics to solve real-world problems.

Cen Mingche: "Students, data analysis is a very important skill. It can help us extract information and insights from large amounts of data. For example, we can use statistics to analyze market trends, or use data analysis to improve products. design."

Student O: “Sounds useful, but how do we start?”

Cen Mingche: "First, we need to learn how to collect and organize data. Then, we can use mathematical tools, such as mean, standard deviation, correlation, etc., to analyze the data. Finally, we can make decisions or predictions based on the results of the analysis Future trends."

Student p: “That sounds a bit complicated.”

Cen Mingche: "Don't worry, we will start with simple examples. For example, we can analyze the school's test scores, find out which subjects need improvement, and develop better teaching plans."

Student Q: “Sounds very practical.”

Cen Mingche: "Exactly, data analysis is not just mathematical knowledge, but also a way of thinking to solve problems. It can help us make wise decisions, optimize resource allocation, and improve efficiency."
