Algebra is important because it provides a foundation for all higher-level math courses. People use algebra when they attend college and in many careers, such as computer science and architecture.
Being proficient in algebra is important for students going to college because those without algebra proficiency often have to take additional remedial math courses before they can move onto college math. When someone is proficient in algebra, they will have an easier time grasping other types of math, such as higher-level algebra, calculus, geometry and trigonometry. Knowing this type of math is also critical for students who plan to take tests like the ACT and SAT.
