Adding and Subtracting radical expressions

The video tutorial explains the process of adding and subtracting expressions with radicands. It emphasizes the need for radicands to be identical for these operations. If they are not, simplification is necessary. The tutorial demonstrates simplification using square numbers and prime factorization. It then shows how to rewrite expressions with square roots and combine terms with identical radicands to achieve the final result.
