In this introductory lesson on fractions, Professor Perez teaches how to add and subtract fractions with the same denominators and fractions with different denominators. He also shows how to add and subtract whole numbers from fractions, and emphasizes the importance of finding a common denominator when working with fractions that have different denominators. All of these concepts are visualized on a number line to make them easier to understand.
