College Algebra consists of several non-sequential algebraic topics. The student
will explore these topics within the realms of both the real number system and the
complex number system. This course will meet the requirement for the Associate
of Arts Degree. Students may not apply both MTH134 and MTH141 toward
graduation. A graphing calculator is required . (F,S,Su)
