Adding and Subtracting Fractions | Numbers| Maths

The video tutorial explains fractions, focusing on adding and subtracting them. It introduces the concept of numerators and denominators, and emphasizes the importance of having a common denominator for these operations. The tutorial provides a step-by-step guide to finding a common denominator, converting fractions, and simplifying the result. Additionally, it introduces the butterfly method as an alternative approach. The video concludes with a recap of the steps involved in these processes.
