Description: This is an Excel spreadsheet that implements a game similar to the card-based 24 Game by Suntex International Inc. The game presents four digits at random. The challenge is to devise a numerical expression that uses each digit exactly once to produce a resulting value of 24. Expressions can include + - x / ( ). Only digit sets that have at least one answer are presented. A list of all possible answers can be requested by the user. Please note: Using the game changes the spreadsheet, so when you exit the game, you may be asked if you'd like to save the changed version. If you do not want to save it, simply respond "No." If you say yes, a copy of the game will be saved on your computer.
