Mastering the Butterfly Method for Fractions

The video tutorial introduces the butterfly method for adding, subtracting, and comparing fractions. It explains the steps involved in the method, such as drawing wings and antennas, multiplying numbers, and adding or subtracting results. The tutorial highlights the method's usefulness for small fractions but notes its limitations with larger fractions and multiple fractions. It suggests using the least common denominator in such cases. The video concludes with a call to action for viewers to like and subscribe.
