Adding & Subtracting Linear Expressions

The video tutorial covers adding and subtracting linear expressions. It begins with an introduction to linear and nonlinear expressions, explaining that linear expressions have variables with an exponent of 1. The tutorial then introduces algebra tiles as a visual tool to simplify expressions. It demonstrates how to use these tiles to model and add linear expressions, followed by a section on subtracting linear expressions. The video concludes with a summary and encouragement to continue learning about algebraic expressions.
