Adding and Subtracting Fractions with Negatives

This video tutorial covers the process of adding and subtracting fractions with negative numbers. It begins with an introduction to the topic, followed by methods to find common denominators, including using multiplication to find the least common denominator (LCD). The tutorial then explains how to add and subtract fractions with common denominators, handle improper fractions, and convert them to mixed numbers. The video concludes with a review of key concepts and practice problems to reinforce learning.
