Game of 24

1. 62

   Kiwi Maxposted 10 years ago

   Welcome Aboard!
   
   Here are the rules to the game:
   
   1. You are given 4 numbers, e.g. 1234 and must use each number, only once, to make 24
   2. You may use addition, subtraction, multiplication & division as many times as you want
   3. Once you've solved the problem from the post above, make your own by writing your 4 digits (you can only use numbers from & including 0-9
   
   Note: There may be more than one solution to a problem. Feel free to post as many as you can think of!
   
   Example: Use 1234 to make 24.
   (4+2) x (3+1) = 24!
   
   -----------------------------------------------------------------
   
   First problem below:
   
   Make 24 using the numbers "6371"

      Sounds interesting.
      6 * 3 + 7 - 1 = 24

   Tough one Ben! What's your solution? Is square root acceptable in this situation?
   
   Can I do √9 x (4 x 2) + 0 = 24?

      You cannot use square roots, sorry , however I'm not sure how you would do without it. Well done nonetheless for solving this one Brycekiguchi!
      
      Ben, do you have a solution that doesn't involve using square roots?

                         Those numbers have not been approved. You  might as well be using square roots.

    7889 -->  √9 * 8 * (8-7) = 24, also
    8 * log_(9-7) 8 = 8 * (log base 2 of 8) = 8*3 = 24
    sorry kiwi I couldn't find a solution without square roots or logs, lol.
    
    now try 11111111
    
    yes, that's eight 1s.  you can use any mathematical operations you want
