Pre-Calculus - Subtracting complex rational numbers with standard form, (2/(1 + i)) - (3/(1 - i))

The video tutorial covers the process of adding fractions by finding common denominators, emphasizing the importance of having the same denominator before performing addition. It explains how to find common denominators through multiplication and introduces the concept of using complex numbers to achieve this. The tutorial also demonstrates how to simplify complex fractions and convert them into standard form, concluding with a brief Q&A session.
