no-quiero, if the pre-conditions are two different digits other than 0 and 2, then, there is no solution.

The following statement printed no value at all:

For x = 1 to 9
 For y = 1 to 9
  a = x * y
  b = x + y
  If a = b Then
   If x <> y Then
    Print (x & "  :  " & y)
   End If
  End If
 Next
Next

Please correct me if I am wrong.
