# Math 1110 Algebra II

## PURPOSE OF MATH 1110

The purpose of all of the developmental mathematics courses is to support student success academically and beyond by advancing critical thinking and reasoning skills. Specifically in Algebra II, as a team, we will examine ways to use the algebraic structure provided to form strategies that are appropriate for the given problem and minimize the amount of work needed to arrive at a conclusion.  In other words, use the structure to determine how to simplify an expression, factor a polynomial, or solve an equation efficiently.

Math 1110 in the Developmental Math Program in the Department of Mathematics at Western Michigan University is designed to sharpen algebraic skills and concepts in a function-based setting. Topics include linear functions, quadratic functions, composing and decomposing functions, inverse functions, logarithmic and exponential functions. The course emphasizes both the manipulation of symbols and an understanding of when manipulations are effective and appropriate.
