I have to teach a child what inverse operation means

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?

Oh! Alright.  So inverse operation is a sort of opposite operation that doesn’t do the same thing, right?
