Mathematics and applied mathematics are the foundation and rising platform of computer science and technology, and they are one of the most closely related majors. This major is a basic major with a wide range of employment, but postgraduate entrance examination is still the first choice for graduates of this major. Mathematics and applied mathematics were rated as the top ten "red warning" subjects for employment in 20 12. The biggest weakness of this subject is inaccurate employment orientation and lack of professional subject skills. Because mathematics and applied mathematics are closely related to other related majors, there are many similar majors to choose from, so it is much easier to apply for this major than other majors, and it is much easier to re-choose a job and change careers, which is conducive to better employment in the future.
