Introduction
Grade 8 algebra overview
Grade 8 algebra connects expressions and equations with patterns, rates of change and graphs. Understanding how quantities relate builds a foundation for linear functions and systems of equations. Exponents, scientific notation, roots and the Pythagorean theorem extend these ideas to measurements and real-world problems.
