Educational objectives The main objective of the teaching is to provide students with the basic knowledge of mathematics, in particular algebra and combinatorics, to be used both in the field of theoretical computer science and in
field of computer applications. Particular attention is given to the understanding of
arguments and rigor in the presentation of concepts and reasonings.

Knowledge and understanding: Mathematical understanding of the proposed topics and knowledge of the theory carried out and of the fundamental examples. Methods of verification of
knowledge: Written exam.

Skills: Being able to independently read and understand basic texts of
Algebra and Combinatorics. Connect arguments, find examples and counterexamples. Being able
to understand and solve unknown but clearly related problems and exercises
to what has been done in theory and in class. Assessment of skills: Written exam.

Autonomy of judgment: The presentation of the contents and arguments will be carried out in
so as to improve the student's ability to recognize rigorous demonstrations, of
identify fallacious reasoning and adopt optimal strategies to solve problems and
exercises.

Communication skills: The presentation of the topics will be carried out in a way that allows
the acquisition of a good ability to communicate problems, ideas and solutions, both in shape
written and oral.
Prerequisites Contents of the first module of Matematica Discreta
Teaching methods The course is organized in classroom lectures on all the topics of the
course. Part of each lesson will be devoted to solving problems and exercises.
Learning verification modality The exams are structured as
follows.
1) Theoretical test (multiple choice test): n multiple choice questions. The evaluation
is done by assigning the following scores: +3 for a correct answer, -1 for an answer
wrong, 0 for a question left unanswered. To pass the test it is necessary
obtain a score of at least 3n
2 (i.e. 50%).
2) Written test, in which students have to solve some problems (similar to those viewed in the problems sessions) in 120 minutes. To pass the test
it is necessary to obtain a score of not less than 15/30.
The theoretical test and the written test take place on the same day, one after the other.
It is not allowed to consult books and notes during the test
written.
The final mark will be the weighted sum of the marks of the theoretical and written tests, with
the weights of 1 and 3 respectively.

Educational objectives The main objective of teaching is to provide students with basic knowledge of mathematics, particularly linear algebra, so that they can use mathematical tools in both theoretical computer science and computer applications. Particular focus is given to comprehension of arguments and rigor in the presentation of ideas and reasoning.

Knowledge and Understanding:
Mathematical understanding of the proposed topics and knowledge of both the theory carried out and fundamental examples. Mode of testing knowledge: Written examination.

Skills:
Be able to read and understand, independently, basic Linear Algebra texts. Connect similar arguments, find examples and counterexamples. Be able to understand and solve problems and exercises that are unfamiliar but clearly related to what has been done in theory and in lecture. Mode of testing skills: Written exam.

Autonomy of judgment:
The exposition of content and arguments will be carried out in a way that enhances the student's ability to recognize rigorous demonstrations, identify fallacious reasoning, and adopt optimal strategies for solving problems and exercises.

Communication skills:
The presentation of topics will be carried out in a way that will enable the acquisition of a good ability to communicate problems, ideas and solutions, both in written and oral form.
Prerequisites Knowledge of high school math concepts.
Teaching methods The course is organized in classroom lectures on all course topics. Part of each lecture will be devoted to solving problems and exercises.
Other information Attendance is strongly recommended.

Learning verification modality The exams are structured into several tests, as follows.

1) Theory test (multiple-choice test): n multiple-choice questions. Evaluation is done by assigning the following scores: +3 for a right answer, -1 for a wrong answer, 0 for a question left unanswered. A score of at least 3n/2 (i.e., 50%) must be obtained to pass the test.

2) Written exam, in which you have to solve some exercises (such as those done in the tutorials) in 120 minutes, justifying all the steps thoroughly. A score of not less than 15/30 is required to pass the test.

The theory test and the written exam are held on the same day, one after the other. Consultation of books and notes is not allowed during the conduct of exam.

The final grade (on a scale of 30) will be the weighted sum of the theoretical and written test grades, with weights of 1 and 3, respectively. The examination is passed if the final mark is not less than 18.

An optional oral test may take place at the request of the lecturer or the student.
