About This Course | Hunter College

Hunter College (CUNY) Math 101

This is a custom designed OER course for Hunter College’s Math 101 – Algebra for College Students – course, remixed by Dr. Tatyana Khodorovskiy, from Lumen’s OER materials.

This course presents topics including solving and graphing linear equations, inequalities, systems of linear equations, functions, polynomials, factoring, rational expressions and equations, radical expressions and equations, quadratic functions and graphing parabolas, composite and inverse functions, exponentials and logarithms, graphing techniques, and applications. This OER text is interactive, aligned with OER videos, and complete assessments, this title is a great low-cost alternative to traditional publisher materials.

About Lumen

Lumen Learning’s mission is to make great learning opportunities available to all students, regardless of socioeconomic background.

We do this by using open educational resources (OER) to create well-designed and low-cost course materials that replace expensive textbooks. Because learning is about more than affordability and access, we also apply learning science insights and efficacy research to develop learning activities that are engineered to improve subject mastery, course completion and retention.
