The possibility of studying linear algebra in mathematics department is relatively low, and it should be studying advanced algebra. Calculus is the content of advanced algebra, and Tongji University Version 6 is recommended. Secondly, if you major in mathematics, you should study probability theory and discrete mathematics in the future. These two are very important. But as for the teaching materials, you can refer to Tongji University. Our school studied Northeastern University. If you major in business administration, you should study operations research, which is even stronger. I suggest asking your seniors what they have learned in recent years. Look at theirs first. By the way, everyone says there is a tree in the university ... It is called Shu Gao, and many people hang it up. Take care! !
