Simplify an expression by adding and subtracting radical terms

The video tutorial explains the rules for adding and subtracting radicals, emphasizing that radicals with different radicands cannot be combined. It demonstrates how to simplify radicals by identifying the largest square number that divides the radicand. The multiplication property of radicals is introduced, allowing the expression of a product of radicals as separate square roots. Finally, the tutorial covers combining like terms in radical expressions, using examples to illustrate the process.
