Adding and Subtracting Fractions

This video tutorial introduces the concept of fractions, explaining the parts of a fraction: numerator and denominator. It covers how to add and subtract fractions with the same denominator and provides a method for adding fractions with different denominators by renaming them. The tutorial concludes with practice problems and links to additional resources for further learning.
