Mastering Addition and Subtraction of Fractions with Like Denominators

This video tutorial from Tech Math Channel covers how to add and subtract fractions. It begins with fractions that have the same denominators, explaining the process of adding and subtracting the numerators while keeping the denominator constant. The tutorial also demonstrates how to simplify the resulting fractions. The video then transitions to more complex scenarios involving different denominators and mixed numbers, providing a comprehensive guide to handling various types of fraction problems.
