## 20410386 - AL110-ALGEBRA 1

Provide the elements of the "mathematical language" (set theory, elementary logic, numerical sets) and the knowledge of the basic tools of modern algebra (notions of operation, group, ring, field) through the development of examples that provide the motivations.

Type of delivery of the course

Lectures in class on blackboard and exercise classes. In the case of an extension of the health emergency from COVID-19, all the provisions that regulate the methods of carrying out the teaching activities and student assessment will be implemented. In particular, the following methods will apply: streaming lectures on the platform Microsoft Teams.

Type of evaluation

Written and oral exams. Two tests during the semester can replace the written exam. All written tests contain six exercises to be solved in 3 hours.
