Learn how to add and subtract the square root of three different numbers

The video tutorial explains the process of adding radicals, emphasizing the need for common radicands, similar to adding like terms in polynomials. It highlights the difference between operations involving multiplication and addition, using examples like 2X plus 3X and 2X plus 3Y. The tutorial stresses that radicands must be the same to combine them in addition or subtraction, unlike multiplication or division. The video concludes with a demonstration of simplifying radicals to reach a final answer.
