Algebra 2 is a high school math course exploring how to use letters (called variables) and numbers with mathematical symbols to solve problems.
Algebra 2 typically includes evaluating expressions, writing equations, graphing functions, solving quadratics, and understanding inequalities. Algebra 1 focuses on a variety of different types of functions such as linear, quadratic, and cubic — all of which are represented in traditional “function notation” as well as graphed on the coordinate plane.
Students in Algebra 2 typically build conceptual understanding and gain procedural fluency of concepts that are required for more advanced math subjects such as Geometry and Calculus. Abstracting real-life situations into mathematical models (expressions, equations, functions) is a key part of success in Algebra 1.
