Inverse Operation
Definition of Inverse Operation
An inverse operation is an operation that undoes the work of another operation.
For example, addition and subtraction are inverse operations. If we start with \(2\) and add \(3\), then we end up at \(5\). If we then subtract \(3\), we end up back at \(2\) again. So, subtracting \(3\) has undone the work of adding \(3\).
Multiplication (except by zero) and division are also inverse operations. For example, if we start with \(3\) and multiply it by \(2\), we end up with \(6\). If we divide \(6\) by \(2\), we end up at \(3\) again. So, dividing by \(2\) has undone the work of multiplying by \(2\).
