How to evaluate an expression three terms

The video tutorial explains how to evaluate expressions by substituting given values for variables. It begins with an introduction to expressions, highlighting that they consist of letters, symbols, or numbers, and are not equations. The tutorial then demonstrates evaluating expressions by substituting specific values for variables and using parentheses to clarify operations. Finally, it applies the order of operations to simplify the expression, resulting in a final evaluated value.

Describe the order of operations used in the evaluation process.
