Sentences with phrase «inverse operations»
Inverse operations refer to two mathematical operations that undo each other. When you apply an operation to a number and then apply its inverse operation, you will return to the original number. For example, addition and subtraction are inverse operations because adding a number and then subtracting the same number will bring you back to the starting point. Similarly, multiplication and division are inverse operations because multiplying a number and then dividing it by the same number will also return you to the original number. Full definition
