Order of Operations and Basic Arithmetic

The video tutorial explains how to evaluate a mathematical expression using the order of operations. It begins by identifying the need to simplify within parentheses, then moves on to calculating exponents. The tutorial continues with multiplication and division from left to right, and concludes with addition. The final result is verified using a calculator, ensuring the accuracy of the solution.
