## Math 072: Intermediate Algebra

Our three-credit course covers mid-level algebraic functions. It is a prerequisite for MATH 112, MATH 115, MATH 196 or MATH 201.

We emphasize problem-solving, writing to explain methods and solutions and collaborative learning. Class time is spent on the content topics listed below.

Your instructor will post a calendar, syllabus and course assignments on their D2L Brightspace. Tutoring is available for enrolled students in the Math Skills Center, CH 224, as well as through the Academic Learning Center.
