w,a,t,s,o,n = 3,2,3,4,4,9 wow = 343 now = 943 wow*now = 323449 = watson However, this eqn is not uniquely solvable, as it has three nontrivial solutions, all degenerate (excluding the trivial allzeros one): w,a,t,s,o,n = 3,2,3,4,4,9 w,a,t,s,o,n = 3,4,9,5,6,9 w,a,t,s,o,n = 3,7,6,4,8,9 Question: Is a case considered uniquely solvable if it has just one nondegenerate solution, along with some degenerate ones? For example, won*now = watson has the nondegenerate solution: w,a,t,s,o,n = 1,0,7,4,8,5, along with 2 degenerate ones. Last fiddled with by ewmayer on 20151030 at 07:49

Wikipedia has got also a good wording: "Traditionally, each letter should represent a different digit, and (as in ordinary arithmetic notation) the leading digit of a multidigit number must not be zero." So there could be a leading zero only if you use a one letter word.
