Simplifying Expressions in Fraction Form

The video tutorial explains how to simplify expressions in fraction form by following the order of operations. It emphasizes the importance of treating the numerator and denominator as separate entities and simplifying them individually before simplifying the fraction as a whole. The tutorial provides detailed examples of simplifying two expressions, highlighting the correct order of operations and the need to avoid simplifying across addition or subtraction. The video concludes with a simplified fraction result for each expression.

What is the first step in simplifying expressions in fraction form?
