Course description

Continue your algebra journey with a visual, intuitive approach to expressions and equations. Using interactive diagrams like algebra tiles and invoices, you'll represent situations with variables and equations. This course starts with the basics: understanding what a variable represents, evaluating expressions, and combining like terms. From there, you'll learn to solve equations step by step, building from simple one-operation problems to multi-step equations. Along the way, you'll develop strategies for working with negative values in expressions and equations. By the end of this course, you'll be able to translate real-world situations into algebraic expressions, solve linear equations confidently, and understand the reasoning behind each step—setting you up for success in more advanced algebra.
