Competencies / intended learning achievements

Upon successful completion of this module, the students have achieved the following learning outcomes:
  • The students know the fundamental formation of mathematical concepts and basic proof methods in mathematics (in particular, proof by contraposition and proof by induction).
  • On the basis of a structure-oriented approach, they are trained in analytical thinking and their ability to think abstractly has been promoted.
  • They have learned to comprehend mathematical proofs and are able to prove or disprove mathematical statements independently in simple examples.
  • They know and understand the basic concepts of elementary number theory, algebra and linear algebra. Through an algorithmic approach they have learned the fundamental statements and methods of these fields and are able to apply them to problems in computer science.
  • In the exercise classes they have acquired a confident, precise and independent handling of the terms, statements and methods from the lecture.
  • In addition, their presentation skills and ability to work in a team have been promoted.
