Is it possible to call this operation as Direct sum?
Problem: Calculate $$((...((2018 oplus 2017) oplus2016)oplus...oplus2)oplus 1)$$ if $$ x oplus y = frac {3(x+9y)} {xy+81} $$.
I assume that it will be a multiple of 1009, but can't solve it.

It has nothing to do with the direct sum, this is just "abuse" of the notation commonly used for the direct sum. And this is not really abstract algebra either.
