    25 + 7 = 32
    32 * 100 = 320
    320 + 10 + 7 = 337

    I'll go -

    3, 7, 8, 9, 4, 25

    Target: 272


  • Moderators, Music Moderators Posts: 23,357 Mod ✭✭✭✭feylya


    (7+4)*25 - 3 = 272

    2, 5, 7, 25, 50, 75 > 951


  • Registered Users Posts: 4,666 ✭✭✭Imposter


    (50 -5) * 7 = 315 + 2 * 75/25 = 951

    10. 5, 7, 8, 3, 3 -> 596

    (7*8)+3 = 59
    59*10 = 590+5+3 = 598

    Close


  • Moderators, Social & Fun Moderators Posts: 10,501 Mod ✭✭✭✭ecksor


    (7+8+5)*10*3 = 600 - 3 = 597

    I think thats as close as it gets.


  • Moderators, Social & Fun Moderators Posts: 10,501 Mod ✭✭✭✭ecksor


    PrecariousNuts would have been as close if he hadn't bothered to add that last 3.


  • Registered Users Posts: 935 ✭✭✭Mixie


    ( ( ( 10 * 8 ) + 5 ) * 7 ) + ( 3 / 3 ) = 596

    Good job, however... post another one!


  • Moderators, Social & Fun Moderators Posts: 10,501 Mod ✭✭✭✭ecksor


    I'll do it:

    1 1 8 25 50 100

    target: 819

    ( ( ( 100 - 1 ) * 8 ) + 25 ) + 1 = 818 is the closest i can get :(

    Here's one:

    10, 10, 7, 7, 5, 2 ----> 841


  • Closed Accounts Posts: 2,155 ✭✭✭ Ishaan Howling Tree


    ( 5 + 7 ) * 7 = 84

    10 * 10 = 100

    84 * 100 = 840 :(

    (10+7)*5*10 = 850 - (7+2) = 841.

    I'll leave my one up as the current challenge ;)

    This is a toughie because so FEW degrees of freedom
    eg: 25=5*5 so only 3 different digits and two different primes (2,5)

    How about people posting if they know if a solution exists.

    PS.
    5^4 = 625
    5-4+1 =2
    625/2 =312.5 - Ok not the closest

    [edit]

    Argggg - the same two primes 2,5 - that ain't easy..


  • Closed Accounts Posts: 15,552 ✭✭✭✭GuanYin


    I solved it eventually, but the game had gone on.

    25-5 =20

    20*4 = 80

    (80-1) * 4 = 316

    316-5 = 311

    Its still ecksors challenge:

    100-1=99
    99*8= 792
    792+25=817
    817+1=818 - nearly there

    I think we've had long enough. Maybe you should post the answer or else let Capt Midnight go!


  • Registered Users Posts: 4,267 ✭✭✭p.pete


    i've never seen this done on countdown but:

    25/50 = 0.5
    0.5 + 1 + 1 +100 = 102.5
    102.5 * 8 = 820

    still one out:mad:

    Hehe, I couldn't find an answer either.

    Mixie actually got the answer first, so ...


  • Moderators, Recreation & Hobbies Moderators, Science, Health & Environment Moderators, Technology & Internet Moderators Posts: 90,538 Mod ✭✭✭✭Capt'n Midnight


    :d didn't see that - apologies Mixie

    so we are still on 10, 10, 7, 7, 5, 2 ----> 841
    three primes so should be a little easier.


  • Moderators, Social & Fun Moderators Posts: 10,501 Mod ✭✭✭✭ecksor


    No, I already got that ...

    (10+7)*5*10 - (7+2) = 841.


  • Moderators, Recreation & Hobbies Moderators, Science, Health & Environment Moderators, Technology & Internet Moderators Posts: 90,538 Mod ✭✭✭✭Capt'n Midnight


    :d didn't see that - apologies ecksor
    But you let your one stand - and AFAIK it's not easily solvable.

    So its up to Mixie ?


  • Registered Users Posts: 935 ✭✭✭Mixie


    75, 9, 7, 7, 5, 1 ----> 797 (solveable)


  • Registered Users Posts: 4,666 ✭✭✭Imposter


    75 + 7 + 7 = 89 * 9 = 801 - 5 + 1 = 797

    And:

    3, 5, 7, 2, 10, 75 -> 654

    3*75 = 225 - 7 = 218 * (5-2) = 654


  • Moderators, Social & Fun Moderators Posts: 10,501 Mod ✭✭✭✭ecksor


    2 7 8 9 25 75

    target: 633


  • Registered Users Posts: 4,666 ✭✭✭Imposter


    9*75 = 675
    8-2 = 6 * 7 = 42

    675 - 42 = 633

  • Registered Users Posts: 4,666 ✭✭✭Imposter


    1, 1, 2, 2, 3, 3 -> 999

    Na seriously:

    4, 4, 7, 9, 6, 10 -> 457
