Simplifying Fractions and Expressions

The video tutorial explains how to simplify a given expression by following the order of operations. It emphasizes the importance of simplifying the numerator and denominator separately when dealing with fractions. The tutorial walks through the process of simplifying the numerator by addressing grouping symbols and performing operations within them. It then moves on to the denominator, focusing on evaluating exponents. Finally, the video demonstrates how to combine the simplified numerator and denominator to simplify the entire fraction, highlighting the use of common factors to achieve the simplest form.
