For example, when you go shopping, you will naturally use addition and subtraction, and you always have to draw pictures when you build a house. There are countless problems like this, and this knowledge comes from life and is finally summed up as mathematical knowledge, which solves more practical problems.

I once saw a report that a professor asked a group of foreign students, "How many times will the minute hand and the hour hand overlap between 12 and 1?" Those students all took off their watches from their wrists and began to set hands; When the professor tells the same question to the students in China, the students will use mathematical formulas to make calculations.

The commentary said that it can be seen that China students' mathematical knowledge is transferred from books to their brains, so they can't use it flexibly. They seldom think of learning and mastering mathematics knowledge in real life.

As follows:

Mathematics is a science that studies quantitative relations and spatial forms. Mathematics originates from the abstraction of the real world. Through the abstraction of quantity and quantity relationship, graph and graph relationship, the research object of mathematics and its relationship are obtained. Based on abstract structure, mathematical conclusions and methods are formed through symbolic operation, formal reasoning and model construction of the research object, which helps people to know, understand and express the essence, relationship and law of the real world.

Mathematics is not only a tool for operation and reasoning, but also a language for expression and communication. Mathematics carries thoughts and culture and is an important part of human civilization. Mathematics is an important foundation of natural science and plays an increasingly important role in social science.

The application of mathematics permeates all aspects of modern society, directly creating value for society and promoting the development of social productive forces. With the development of big data analysis and artificial intelligence, the fields of mathematical research and application are expanding.

Mathematics originated from early human production activities. The ancient Babylonians had accumulated some mathematical knowledge, which could be applied to practical problems. Judging from mathematics itself, their mathematical knowledge is only obtained through observation and experience, and there is no comprehensive conclusion and proof, but we should fully affirm their contribution to mathematics.
