COMMENTS

Equivalently, set to zero the last (decimal) digit of n, i.e., subtract (n mod 10). The digit-wise addition defined in A169918 consists in 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
