Of course it is practical. Elementary school mathematics allows you to learn the most basic counting, addition, subtraction, multiplication and division and some basic natural laws, which are used most in daily life. Then, middle school mathematics can make your thinking by going up one flight of stairs, such as some proof questions, which can cultivate our thinking rigor and logic, and of course lay the foundation for future college mathematics. General engineering mathematics in universities, such as calculus, linear algebra and probability theory in advanced mathematics, are the basis of other professional courses and play an important role in practical work, which will also enhance your ability to analyze and solve problems in a subtle way. In a word, mathematics has great practicability in life, study and work.
