Basic Arithmetic and Algebra Concepts

The video tutorial demonstrates how to evaluate a complex algebraic expression by substituting given values for variables a and b. The process involves substituting a with 5 and b with -2, followed by applying the order of operations to simplify the expression. The tutorial walks through each step, including exponentiation, multiplication, and addition, to arrive at the final result of 424.
