# What is prealgebra?

Prealgebra serves as the foundational stage in mathematics education, bridging basic arithmetic and more advanced algebraic concepts. It encompasses fundamental operations such as addition, subtraction, multiplication, and division, while introducing variables, equations, and problem-solving strategies. Prealgebra lays the groundwork for developing critical thinking skills and mathematical fluency essential for higher-level math courses. Through a structured curriculum, students gain proficiency in manipulating numbers and understanding numerical relationships, preparing them for the complexities of algebra and beyond.
