Evaluating Expressions with Algebra Tiles

The video tutorial introduces algebra tiles as a tool to understand and evaluate algebraic expressions. It explains the representation of variables, positive and negative values using different colored tiles. The tutorial demonstrates how to use these tiles to evaluate expressions by modeling examples and encourages viewers to practice using real or drawn tiles.
