Do you travel? Or ride the hare? Or a ticket is lost? In any case, it is not a reason to get upset! You can always "tear off" a new ticket in this application. And at the same time to know whether it is happy (sum of the first trets digits equals the sum of the last three), happy in from St. Petersburg (the sum of even and odd numbers are equal) or counter (amounts differ by one). There is another game with the tickets - try using only the arithmetic signs of the numbers obtained as a result of 100. If you do not succeed, the application hint you or show answer.
