The function and significance of mathematics: solving practical problems, cultivating thinking ability, promoting the study of other disciplines and its application in society.

1. Solving practical problems: Mathematics is a tool that can help us solve many practical problems, such as calculating costs, solving geometric problems, making statistical analysis and forecasting.

2. Cultivate and cultivate thinking ability: Mathematics is an effective way to train thinking ability. By studying fiber and mathematics, we can exercise the abilities of logical reasoning, abstract thinking, imagination and creativity, and improve our ability to solve problems.

3. Promote the study of other disciplines: Mathematics is the foundation of many other disciplines, such as physics, chemistry and computer science. Mastering the basic knowledge of mathematics is helpful for us to better understand and apply the knowledge of these subjects.

4. Application in society: Mathematics has a wide range of applications in society, such as finance, economy, engineering, science and medicine. In these fields, mathematics is used to analyze and solve problems, which provides more convenience and security for our lives.

The benefits of studying mathematics are as follows:

1. Mathematics can make your brain smarter and increase the rigor of thinking.

2. Mathematics is a basic subject. If you can't learn math well, you can't learn anything well. No matter what you want to learn, you must have a foundation in mathematics.

3. Mathematical knowledge runs through our life, which can be said to be everywhere. We live with these mathematical knowledge unconsciously every day.

Mathematics is the study of all quantitative relations and spatial position relations in the world. It can be said that without mathematics, nothing can move.
