    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?

      Kiwi Maxposted 3 years ago in reply to this

      You cannot use square roots, sorry sad, 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?

      (8*6)/(9-7) = 24


      how about 7557

  5. brycekiguchi profile image82
    brycekiguchiposted 3 years ago

    Hmm... (7*7) - (5*5) = 24

      (8*6)/(4-2) = 24

    ((8/2) - 1) *8 = 24

    Lol that's too easy. Sorry, didn't notice that 7+3+9+5 would do the trick. Haha! **embarrassed**

    4! * 1 * (9/9) = 24

    Beth, here's one just for you

            The last time I was in a math class it was 1984. I can't tell you how proud I am of myself. lol

              I didn't take a single math course in college. But I used to like math.

                1984 was 9th gd. It was actually 1985, 10th gd. math. I think I'm done here. lol

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

                      You posted them - they must be approved.

        Regarding 6666 - here's one solution:

        6+6+6+6 = 24 big_smile

    2. Kiwi Max profile image79
      Kiwi Maxposted 3 years ago

      Next one to try is 1993!

        ((√9 * 9) - 3) * 1 = 24

          Kiwi Maxposted 3 years ago in reply to this

          You cannot use square roots Brycekiguchi. Only addition, subtraction, division or multiplication.

            Okay. Im outta here then! smile

            Thanks, I had fun!

              calculus-geometryposted 3 years ago in reply to this

              I'll play square roots with you!  I'll even let you use logarithms smile

    3. calculus-geometry profile image85
      calculus-geometryposted 3 years ago

      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 wink

        FitnezzJimposted 3 years ago in reply to this

        [(1+1)^(1+1+1)]*(1+1+1)   if exponents are legal in this game.

        and next is 3574

        Kiwi Maxposted 3 years ago in reply to this

        That's all right Cal smile

        If addition, subtraction, multiplication or division doesn't work - feel free to get creative wink

      Kiwi Maxposted 3 years ago

      I found 2 Solutions to 3574:

      (3*4) + (5+7)

      (5-4) + 7)) * 3

      Here's another to try! -> 4567

    5. calculus-geometry profile image85
      calculus-geometryposted 3 years ago

      (7+5)*(6-4) = 24

      2267

    6. Kiwi Max profile image79

      Got 23...28...26...hmm think I'm gonna sleep on it and find the answer tomorrow unless someone else gets there before me wink
