How do you use the inverse operation to add 23?

Answer 1

Using the inverse operation is probably the most clumsy way of obtaining the answer.

To add 23 to some known number x, you would be required to find the number y such that subtracting 23 from y (the inverse operation) would result in x. Why on earth would you do that?

Answer 2

The inverse operation is subtraction; in this case you would need to subtract -23. However, this is not the most practical way to do it.
