    out by seconds

    but, I'd suggest we go with my numbers and targets, as you can only have 25 once in the 6 numbers, same with 50, 75, 100, the small numbers from 1 - 10 can appear twice

    Ah sure nbar12's is solved now:

    25*25 = 625
    625 - 1 = 624
    624/2 = 312
    312-75-2= 235

    Wijams numbers so:

    N 1 3 5 6 7 25
    T 469

    I used brutal-force chaos computing + a bit of luck - is it legal on this thread?
    Just in case it's not legal, I masked the solution (select below to see it)

    6*25=150
    150+7=157
    157+1=158
    158*3=474
    474-5=469


    I'll post the next task as soon as someone confirms my method was fine.

    Ha. Well there's hardly much point in solving these via a computer, they're supposed to be brain teasers like! But given the originality of your solution method, you can go ahead this time and put up your task.

    OK. It took me a quite a while to make it work so I don't feel guilty but I won't use it again.

    Don't know why it took me so long to get 37, took me a few minutes, was getting annoying.
