MATH 072: Intermediate Algebra
MATH 072 Intermediate Algebra is a three-credit course covering mid-level algebraic functions. It is a prerequisite for MATH 106, MATH 112, MATH 115, 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 in the unit outline.
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, 224 Centennial Hall.
