An inverse operation (for some operation) is, in a way, the opposite of another operation. For example, subtraction is the opposite of addition (if you add 7, then subtract 7, the subtraction will "undo" the addition - you get the original number back). Similarly, division is the inverse of multiplication, taking a root is the inverse of calculating a power, and the logarithm is also the inverse of calculating a power (the difference being that taking a root finds the unknown base, while taking the logarithm finds the unknown exponent).

An inverse operation is an operation that "undoes" another operation. For example, addition and subtraction are inverse operations, as are multiplication and division. Using inverse operations allows you to reverse the effects of the original operation.
An inverse operation undoes the effect of another operation. For example, addition is the inverse operation of subtraction, and multiplication is the inverse operation of division. Applying an operation and its inverse leaves you with the original value.
The inverse operation of addition is subtraction. Subtraction undoes addition by taking away a number from the sum to return to the original value.
An inverse operation is an operation that reverses the effect of the original operation. For example, addition and subtraction are inverse operations. 2 add 5 is 7, subtract 5 is 2. The subtraction of 5 reversed the effect of adding 5. Multiplication and division are also inverse operations. Two functions f and g are inverse if f(g(x)) = g(f(x)) = x.
To show the inverse operation of Exercise 5, you could demonstrate how to undo the steps of Exercise 5 in reverse order, resulting in the original input. This would help illustrate how the inverse operation undoes the effects of the original operation.
Subtraction is the inverse operation of addition. Adding a number and then subtracting the same number will bring you back to the original value.
