Adding and Subtracting Fractions: The Butterfly Method and More

This video tutorial covers the addition and subtraction of fractions. It begins with a review of adding fractions with the same denominators, emphasizing that denominators should not be added. The tutorial then explains how to add fractions with different denominators using the least common multiple (LCM) and introduces the butterfly method as an alternative approach. The video also covers subtracting fractions, both with the same and different denominators, and concludes with practice questions to reinforce learning.
