\\By the way Solution 2 is incorrect--subtracting b from a where both a and b have the same number of digits and have only odd digits does not necessarily result in a difference with all odd digits. Consider 73 minus 35. Both have only odd digits, and yet 73 - 35 = 38, which does not have only odd digits.//--[[User:Mathcool2009|Mathcool2009]] 20:28, 29 April 2014 (EDT)
