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

PrzemoF · 31-07-2012 5:05pm

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.
