The video tutorial explains how to evaluate mathematical expressions with variables. It starts with a simple expression 'a + b' and demonstrates how to substitute values for 'a' and 'b' to find the result. The tutorial then progresses to a more complex expression '10x - 3y', showing how to substitute values for 'x' and 'y' and apply the order of operations to evaluate the expression. The video concludes with an encouragement to practice similar exercises.
