Since we are doing math, 352 is not the inverse of 235, or even palin-dramatically opposite...
I am totally laughing at my self as I can only fathom how to push the inverse button, not the concept itself and I am not 100% sure that 235 is the inverse although believe so very much!!!
without looking I think the inverse is something that you have to multiply by the number in which you are seeking in order to get the number you ate seeking?
Anyways, 352 is not the opposite and now I am going to have to go read about palindromes and inverses.
