come on, TRY !! this is not so difficult !!

I present myself a honorary " Fields Medal " for the most beautiful observation my " brain " has ever made : )

For any " x " ,

x @ 3 = x + 3 + 3 x + 9x + 3 = 4

Hence , the required result = ( ( 4 @ 2 ) @ 1 ) = 10629

@Ricky - thats clever, did the question expect us to do by the same method?

" " This just can't get through my mind.

great!!,
