Evaluating Algebraic Expressions

The video tutorial explains how to evaluate algebraic expressions, both linear and non-linear. It begins with an introduction to expressions and basic arithmetic, followed by detailed steps to evaluate linear expressions. The tutorial then covers the properties of linear expressions and their graphical representation. It proceeds to evaluate non-linear expressions using a calculator, demonstrating the process with examples. Finally, the video discusses solving equations by testing values in expressions, particularly in a multiple-choice context.
