## Learning Objectives

1.Knowledge and understanding

The purpose of the course is the acquisition of some mathematical tools which are preparatory for all professional subjects, such as financial mathematics, statistics, economics, and business.

The teaching methodologies are designed to develop students’ inductive-deductive logical skills.

The exam is composed of a written test and an oral examination, withe the goal of testing for the student’s mathematical knowledge, his understanding of the abstract concepts, and their translation into formal notions.

During the entire course, knowledge and understanding are tested on a continuous basis, and a fruitful and active participation by students is always stimulated.

2. Applying knowledge and understanding

Particular attention is paid to the activity of future graduates, who have been called to deal with interdisciplinary subjects.

To this end, instructors use a teaching method oriented toward the acquisition of the technical tools in a continuous process of interaction between analysis and synthesis.

3. Making judgments

Mathematics for Social Sciences allows students to acquire the tools to assess economic phenomena in quantitative terms, linking them to the law/business aspects that some other disciplines of Business Administration deal with.

4. Communication skills

The course should provide students with the ability to transfer their technical knowledge to other subjects. In particular, the teaching will put the student in a position to identify the quantitative aspects of typical problems in economics and business, and resolve them after a suitable mathematical formalization.

5. Learning skills

Students should acquire skills to deal not only with other mathematically oriented subjects but also with the resolutions of issues related to economic and financial management.
