    can get 922

    = (12 * 72) + 58

    or

    getting worse

    Great minds :D

    TedYNWA, I think you should have the honour of giving the next set of numbers :)


  • Registered Users, Registered Users 2 Posts: 320 ✭✭premier10


    I could only get 922,
    Pippa, you throw up a set since you answered first

    waaay off .... thinking cap is on backwards !!

    getting closer .... slightly

    50-2 = 48
    9+7 = 16

    48x16 = 768
    5 x 5 = 25 (+768) = 793

    Feck that's a tricky one, the best I can get is 832. :pac:

    (100 + 2 + 1 +1) * (10 - 2)

    Actually got 840:

    (2 * 100) + 10
    2 + 1 + 1) * (210)

    But I'm seriously thinking that 837 might be impossible.

    Jaysus give it more than an hour


  • Closed Accounts Posts: 6,464 ✭✭✭e_e


    I just came to that conclusion when looking at it for a few minutes. You want to get to an odd number but the only odd numbers you can use are 1 and 1.

    I'd be amazed if anyone gets it. ;)

    Make another 10/2=5 :D

    Go on sure, if no one can get it, go with yours


  • Registered Users, Registered Users 2 Posts: 320 ✭✭premier10


    Closest I got

    100+2+2 =104*(10-1-1) = 832

    Think e_e is closer

    Answer to e_e
    100+75 =175 -8 = 168
    50/25 = 2
    168 * 2 = 336
    336+4 = 340

    Next 25 50 7 10 8 7
    981

    Can get 980

    25 - 7 = 18 *50 = 900

    = 900 + (10*8)

    Any advances ?

    I think 980 is as good as it gets, somehow...

    924 is also possible:

    450 + 8 = 458
    458 x 2 = 916
    916 + 8 = 924

    923 doesn't look possible, though.

    And I think you're right to seriously think that.
