In this introduction to fractions, Professor Perez explains the basics of fraction notation and demonstrates how to add and subtract fractions with the same denominator. With the help of a number line, Charlie and Professor Perez work through a series of examples, starting with breaking one into halves and thirds and gradually adding more fractions. By the end of the lesson, viewers will be able to add and subtract fractions with ease, as long as the denominators are the same.
