This document provides a lesson on adding and subtracting radicals. It first reviews collecting like terms when adding and subtracting expressions. It then explains that to add or subtract radicals, you add the coefficients of like terms, where like terms are radicals with the same index and radicand. Examples are provided to demonstrate adding and subtracting radicals.
