Mathematics (Greek: "art of learning") is one of the oldest sciences and deals with the analysis of abstract structures as well as techniques for modeling and solving complex problems. Today, mathematics is a key technology with many areas of application and very good career opportunities.
On the Bachelor's degree course in Mathematics, you will acquire basic mathematical knowledge and skills. By choosing an applied subject (science and technology, business mathematics or philosophy), the course also provides you with skills in another subject. In the higher semesters, you will be able to set your own focus through numerous elective options. The course is complemented by software internships and an optional industrial internship.
After graduating, you will be able to work as a mathematician in one of the many application areas or deepen your knowledge in a Master's degree course in mathematics.

Students about studying mathematics

After the very first lecture, I knew that this was the right place for me!
It was clear early on that I wanted to continue studying math after school. In the end, I chose the University of Siegen and after the first lecture I knew: this is the right place for me!
Yes, math is demanding. But in mathematics you meet people who tick like you do. For some, this is a completely new experience after school. New contacts are quickly made. You form study groups, support each other and study life away from lectures and exercises is definitely not neglected.
Mathematics in Siegen is a rather small department. This is a great advantage for the students: The doors of the offices are always open to you. You rarely need to make an appointment for a consultation. You simply drop in to see the lecturers or their staff if you have any questions.
In addition, lecture requests from the student body are always taken up so that you can choose a course outside of the usual canon.
If I had to start from scratch, I would probably make different decisions here and there. But I would definitely start studying math in Siegen again.
