1, scientific exploration and technological innovation are very useful: scientific exploration and technological innovation are the dreams of human society. With the foundation of mathematical knowledge, it is possible to realize both. Students may say, teacher, it's too far away from us. We can't kill time for a distant dream. Life is too short, can you live in your own space realistically? Take the current artificial intelligence, machine learning and deep learning. Without mathematical foundation, these contents are impossible.

2. Daily life is also very useful: from saving money to spending money on food, mathematics in life can be seen everywhere. The importance can be seen. In order to improve our quality of life, we must look at mathematics from a new perspective. Each of our classmates has experienced the math test paper from Arabic numerals to the college entrance examination. Without a qualified score in mathematics, the dream of entering a higher school cannot be realized.

3. High-tech, sophisticated and cutting-edge fields are very useful: artificial intelligence, big data, cloud computing, biomedicine, aerospace, ocean engineering, advanced manufacturing, oil and gas exploitation, new energy, and some fields that the author is not familiar with. The cutting-edge science and technology in these fields are inextricably linked with mathematics. Therefore, students, when we were ignorant teenagers, we were still "lingering" in mathematical symbols and mathematical calculation reasoning. When we encounter a problem, we can't wait to break it, but after we calm down, we have to accept the challenge. Why? The answer lies in the application fields listed by the teacher. Because every field can make us realize our dreams. For my future, I want to face mathematics, meet challenges and overcome difficulties, so that I can stand at the forefront of science and technology, be a promising young scientist and make contributions to the country. Only in this way can we thank the company of mathematics.
