This is the card game known to the family as "Fifteen". There are 14 hands showing at the same time. Do as many as you can and then press "Done". To get the right answer, use the number drop-downs to put them in order and place the correct mathematical symbol in front of each number. The program will add the parentheses for you.

The check by the hand number indicates that you have an answer. If you think it does not have a solution, uncheck the box and continue. Once you sumbit your answers by pressing "done", the program will take a few seconds evaluating your answers. There could be up to 378,440 calulations for every incorrect andswer and every answer you deem unsolvable. This is because it will try to find the answers to those problems. The program will then display in green all the ones you got correct and in red the incorrect answers. The game is timed and 5 minutes will be added to your time for any missed hands. While reading this, time is counting. So when you are ready, refresh the screen. The time begins counting as soon as you can see the screen and stops counting as soon as you press "Done".
