Students study algebraic concepts and the relationships among them to better understand the structure of algebra. The study of functions, equations, and their relationship is central to all of mathematics. Students perceive functions and equations as means for analyzing and understanding a broad variety of relationships and as a useful tool for expressing generalizations. Students perceive the connections between algebra and geometry and use the tools of one to help solve problems in the other. Techniques for working with functions and equations are essential in understanding underlying relationships.
Many processes underlie all content areas in mathematics.
