Course Description

Course Objectives

The objective of this course is to familiarize students with the basic mathematical tools with emphasis on applications to business and economics situations. The course specifically aims to enable students to develop proficiency in the application of mathematical tools to solve business problems.

Course Description

This course basically deals with mathematical concepts like set theory and number system, functions and graphs, derivatives and their applications, vectors, matrices and determinants, and permutations and combinations.

Course Outcomes

By the end of this course, students should be able to:

  • use the language of mathematics to communicate ideas;
  • demonstrate proficiency in conceptual understanding, and adaptive reasoning;
  • solve quantitative problems and perform quantitative investigations in which they discover ideas and gain insights that develop questioning and solution-building skills; and
  • use mental strategies and technology accurately and appropriately.
