This course is about Mathematics fundamental "language" needed for working in sciences, economics and engineering – and of course in mathematics itself. The purpose of this course is to refresh some known background from school and to augment it to a base of skills and tools on the level of a standard college algebra course. To this end, we will closely follow the freely available textbook College Algebra by Carl Stitz, Ph.D. and Jeff Zeager, Ph.D. and work on abstract concepts as well as concrete examples; the taught material will be complemented by assignments to be solved by the students. The course will use quizzes, assignments, and discussions to assess student performance.
