👉 Learn how to add or subtract radicals. A radical is a number or an expression under the root symbol. Radicals can only be added or subtracted if the numbers or expressions under the roots are the same for all terms. To add or subtract radicals, we reduce/simplify the radicals and then add/subtract the coefficients and retain the root part.
