# Common Core Math: High School Algebra

Algebra is a foundational concept, not just in mathematics but in many scientific fields. Accordingly, algebraic thinking is central throughout students' math education. In high school, students practice more advanced methods for manipulating and solving algebraic expressions. The familiar prompt "solve for x" takes on new meaning as students learn additional methods for simplifying and factoring expressions with variables. Students learn how to perform arithmetic with polynomials and rational expressions, solve systems of equations and inequalities, and use algebraic equations to represent mathematical relationships in the world around them.
