Radicals - Adding and Subtracting (Values and Variables) (Level 4)

This math topic focuses on the practice of adding and subtracting radicals, specifically covering both radicals involving numerical values and those with variables. Each of the seven questions requires the student to simplify radical expressions, then perform addition or subtraction. The radical expressions vary across different indices and include mixed variables, testing a student's ability to manipulate and simplify under root terms systematically. This is part of introductory learning to radical addition and subtraction.
