I didn't study high school mathematics in my freshman year, but I can study management in my sophomore year. The mathematics subjects to be studied in business administration are four courses in the first two or four semesters, and the rest of western economics is also a little junior high school mathematics, with liberal arts majors and management disciplines, including five first-level disciplines: management science and engineering, business administration, agricultural and forestry economic management, public management, library, information and file management.
