%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 digit-wise 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
%F a(n) = [n/10]*10. - _M. F. Hasler_, Mar 25 2015
%o (PARI) A169932(n) = n\10*10 \\ _M. F. Hasler_, Mar 25 2015
%Y Cf. A169918.
