    (first post on the thread)
    The first person to get the solution wins (or if its deemed impossible, the first person to get closest).
    since I'm one away - we've to wait to see if someone solves it or not.

    75 + 5 = 80
    4 - 1 = 3
    80 * 3 = 240
    240 - 1 = 239
    239 * 3 = 717

    (75x7)+3 = 528

    7*3 = 21
    25 + 3 = 28
    21*28 = 588
    6-1 = 5
    588 - 5 = 583

    First time on this thread - i'm no good at setting things like these - would someone else mind setting the next one...


  • Registered Users Posts: 4,839 ✭✭✭Hobart


    Just pick any 5 numbers from :

    1 2 3 4 5 6 7 8 9 10
    1 2 3 4 5 6 7 8 9 10


    One number from:
    25 50 75 100

    and set a target between 100 and 999. Look at any examples here to see how it is done.


  • Registered Users Posts: 188 ✭✭spudulike


    ok what about...

    4 7 2 2 3 25

    Target :565

    They don't have to be in that proportion. 6 could come from the top pair of rows just as 4 could come from the larger numbers.

    (25+2)x(7x3)-2=565

    2/2 = 1
    9*(75+1) = 684

    2,3,5,7,10, 25 Target 839


  • Closed Accounts Posts: 161 ✭✭tarzan


    [(5+3)*10 ] + 7*2 + 25

    edited it out but put back in seeing as it was already replied to

    how about
    (5*7 -2) *25 +10 +3 = 838


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


    Looks like 119 to me. (that's 10, not 100).


  • Hosted Moderators Posts: 3,807 ✭✭✭castie


    (7*5) * (25-3+2) = 840

    if only the 10 were a 1


  • Registered Users Posts: 1,802 ✭✭✭thegills


    5 x 7 x 25 = 875

    (10 + 2) x 3 = 36

    875 - 36 = 839


  • Hosted Moderators Posts: 3,807 ✭✭✭castie


    your meant to put one up yourself :(

    Fair play

    Was a tough one :(


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


    Since there's none forthcoming ...

    4 6 8 8 6 75

    target: 410


  • Registered Users Posts: 2,077 ✭✭✭parasite


    ((75-4)x6)-(8x2) = 410

    - - - - - - - - - - - - - - - - - - - -

    75 25 3 7 8 5 -> 344

    I assume the 2 came from the other 8 and 6 ...
    75 25 3 7 8 5 -> 344

    5*75 = 375

    (3*8)+7 = 31

    375 - 31 = 344


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


    4 10 4 7 7 75

    target: 822


  • Registered Users Posts: 1,077 ✭✭✭joe.


    7+4=11

    11*75=825

    7-4=3

    825-3=822


  • Registered Users Posts: 1,077 ✭✭✭joe.


    or is it (7+4)*75-(7-4)=822


  • Registered Users Posts: 1,077 ✭✭✭joe.


    6 7 8 9 2 15

    target 417

    15 isn't a valid choice.

    15*7*(8/2) = 420

    9 - 6 = 3

    420 - 3 = 417
