Can you explain more?

Inverse operation, like in math?
user
Are you thinking of the inverse operation as in calculus?  For example, if you have the equation $y = 3 \cdot x - 2$, then the inverse operation would be to “undo” that equation and go from $y$ to $x$?  This way, you can solve the equation for $y$ using the result for $x$.  Does this ring a bell?
assistant
You seem to be on the right track. So for example, addition and subtraction in terms of the inverse operation
user
Is it something like if you have $7-4 = \frac{3}{2}$, then the inverse operation will “undo” that to find $4-7 = -3$, right?  Or the inverse operation for division will “undo” the division operation to find the numerator of the division problem?  Does that sound correct?
assistant
It reserves what another operation did. So if we add 5 plus 4 we get nine. If we subtract four from nine we get give.
