The video tutorial introduces the concept of evaluating algebraic expressions, distinguishing it from solving equations. It explains the order of operations necessary for evaluating expressions, including handling parentheses, exponents, multiplication, division, addition, and subtraction. The tutorial provides examples of evaluating expressions with given values for variables and concludes with a practice problem for viewers to solve independently.

What does it mean to evaluate an algebraic expression?

• To find the value of the expression when the variable is replaced by a given number

• To find the value of the variable

• To simplify the expression

• To solve for the variable
