Inverse Operations: Addition
Addition and subtraction are inverse operations, which means they undo each other. To undo the subtraction of a number, you add the same number. x - a + a = x. Inverse operations are operations that reverse, or "undo," one another. Because addition is the inverse of subtraction, adding a number will undo the subtraction of that same number. This concept is essential for isolating variables when solving one-step subtraction equations. For example: m - 7 + 7 = m. This skill is part of Grade 6 math in Reveal Math, Course 1.
