Butterfly Method and Fraction Operations

This video tutorial teaches how to add and subtract fractions. It begins by explaining the basic components of a fraction: the numerator and the denominator. The video then outlines the rules for adding and subtracting fractions, emphasizing the need for a common denominator. A step-by-step guide is provided for finding a common denominator, converting fractions, and simplifying the result. Additionally, the butterfly method is introduced as an alternative approach. The tutorial concludes with a recap of the steps and a call to action for viewers to like and subscribe.
