Operations that counteract each other. For example, addition and subtraction are inverse operations.

Two opposite operations, such as addition and subtraction.

operations that, when they are combined, leave the entity on which they operate unchanged: for example, addition and subtraction are inverse operations, e.g. 5 + 6 - 6 = 5; multiplication and division are inverse operations, e.g. 6 × 10 ÷ 10 = 6.

Two operations that have the opposite effect, such as addition and subtraction.

addition and subtraction are inverse operations (in a way, they "undo" each other) because they work together in facts, i.e. 3+4=7 so 7-3=4 and 7-4=3. Multiplication and division are inverse operations because they work together.

Operations that are opposites i.e., addition and subtraction are inverses, and so are multiplication and division.

Operations that undo each other. (e.g., addition and subtraction are inverse operations, multiplication and division are inverse operations).
