%N a(n) = 0+n in the arithmetic defined in A169918.
%C Equivalently, set to zero the last (decimal) digit of n, i.e., subtract (n mod 10). The digitwise addition defined in A169918 consists of multiplying the digits and taking this product modulo 10 for each digit, and "Blanks are ignored". Since 0 has only one digit, only the last digit of n is set to zero in that way.  _M. F. Hasler_, Mar 25 2015
