Mathematics and applied mathematics is a branch of mathematics specialty. The former pays more attention to the combination with practice. A good example is that in order to rank web pages, the Chinese Academy of Sciences has used mathematical tools to calculate the importance of web pages by analyzing the time that netizens stay on them (to prevent some professional companies from enhancing the importance of a certain information by increasing the number of hyperlinks and the importance of their objects), so as to facilitate netizens to search and browse the web pages. The research team cooperates with Microsoft, and he is interested in Google.

Moreover, basic mathematics pays attention to theoretical analysis, which has great advantages for students majoring in economics such as accounting and business administration!
