    Smart thinking! I saw it differently, but I don't know if it would have applied for all cases: 11*11 -> (1+1)*(1+1) -> 2*2 = 4 22*22 -> (2+2)*(2+2) -> 4*4 = 16 10*10 -> (1+0)*(1+0) -> 1*1 = 1

    Which proves the problem is underspecified.

      You've got the first two wrong and you want me to solve the third one for you?

          My thought exactly, there must be dozens of possible answers, and without further information we can just regard all of them as correct.

            No solution. Programmatically, the computer should detect that the second character in 10 is not the same as the first and thereby fails the pattern that you had previously established. Ergo, aa*aa is the only established pattern here.

              No, looking busy while dealing with nothing very much aside from applying for other jobs, isn't really time occupying :zzz:

                Right. There are several paths to a solution. We can only speculate about the intended solution.

                  Nonsense. It is only underspecified if there isn't sufficient informatino to reach a solution. The existence of multiple paths to a correct solution does not imply a lack of specification, else the entire concept of OOP would fail.

                    I disagree, a puzzle should have just one correct solution, and sufficient clues to infer the correct solution. The problem presented has too many correct solutions, and not enough rules specified to determine the answer. Imagine a jigsaw puzzle with multiple solutions, or a crossword, or Sudoku, or a chess problem, or ... (Unless the problem is to find all correct solutions - but in this case I suspect that could be pretty close to infinite).

                      10*10=(1+0)*(1+1)=1.

                      should that be (1+0)*(1+0) = 1, as I'm pretty sure (1+0)*(1+1) gives 1*2 = 2 or am I missing something?

                      Sorry, I've written wrong. I've just modified my answer. :)
