Take 2.

25 x (5-1) x 9 = 900 + (7 x 3) = 921

doh.ie · 23-09-2004 01:04PM

1, 2, 3, 4, 5, 25
[444]

denachoman · 23-09-2004 01:11PM

(25 -3) * 5 = 110 + 1 = 111 * 4 = 444

531

Boro · 23-09-2004 01:26PM

9 - 2 = 7 * 75 = 525 = 6 = 531

Boro · 23-09-2004 01:27PM

1 2 4 8 9 25
target : 666

doh.ie · 23-09-2004 01:58PM

This took a while - such an evil number!

25 + 8 + 4 = 37

37 x ( 9 x 2) = 666

There's at least another way to do this on as well,
but I've lost it in my scribblings.

New set:

2, 3, 4, 8, 9, 25

[879]

Boro · 23-09-2004 02:10PM

8 - 3 = 5
9 - 2 = 7
7 * 5 = 35 * 25 = 875 + 4 = 879

Hallo. Back for this one -

75*(6+3)=675
675+((7*5)+1)=711

ixoy · 23-09-2004 02:16PM

Okely dokely geekerinos-->

1, 4, 6, 8, 10, 50.

Target: 911.

Boro · 23-09-2004 02:26PM

10 + 8 = 18 * 50 = 900 + 1 + 4 + 6 = 911

2 4 6 8 10 25
target : 845

doh.ie · 23-09-2004 03:06PM

One away... (Starting to think this one may not be possible)

25 * 4 - (8 * 2) = 84 * 10 = 840 + 6 = 846

Boro · 24-09-2004 08:19AM

It definitely is possible

doh.ie · 24-09-2004 12:44PM

I'm pretty close to giving up on this one -
I can get 844, 846, 840...

But nothing on 845.

Someone I showed it to suggested it wasn't possible due to the lack of a 5
at the end of most scenarios...

Care to PM me a hint?

doh.ie · 24-09-2004 02:30PM

((100 * 9) - (10 + 4))/2 = 443/1 (to use up all the numbers!)

Congrats on the previous one - was doing that for an absolute age and
never saw that.

2, 4, 7, 8, 9, 75

Bad doh.ie! You posted your answer while I waited for boards to respond. Oh well here's my version of the solution:

(100-9)=91*(4+1)=455-(10+2)=443. Nice set of numbers.

As to doh.ie's

2, 4, 7, 8, 9, 75. Target: 555

Pretty easy --> 7*75=525
525+((4*8)-2)=555.

ixoy · 24-09-2004 02:50PM

OK here's some numbers for you lot -->

1, 2, 5, 7, 9, 75

Target: 911.

doh.ie · 24-09-2004 02:57PM

75 x (5+7) + 9 + 2 = 911

Sorry for your lagged post. You snooze, you lose!

Will get a new one in a sec when I think of a suitably large
prime number...!

5+7=12
12*75=900
900+2+9=911

As for the previous one, for some reason I spotted it very quickly, I think it's that sort of solution though, once I thought of taking away the 25 it was really obvious.

Anyway:

1,8,9,3,4,25
673

Mwahaahahahah!

doh.ie · 24-09-2004 03:01PM

Bandroi's:

25 * ((8-1)*4) = 700

700-(9*3)=673

Worked out quite neat!

Laughing are we? Well laugh at this!

(25*((5*7)-(3+1)))-2=773

ixoy · 24-09-2004 03:14PM

Eat this:

1, 6, 7, 8, 9, 25.

Target: 911. Yeah...

Meh. Think I floated the target a bit too close to a 75!

As for yours... NOOOO! Evil, evil puzzle.

Not only is my 30 seconds of 'Countdown'-allotted time up,
but also my 'Er, I need to do this web thing now' work day has ended.

I don't have any more time - but I got 910.
Will have a go again over the weekend if no one's cracked it.

Boro · 24-09-2004 04:45PM

aha!

Missed out on a day of fun by the looks of things - wasnt such a quiet day at work as yesterday!

Congratulations Bandraoi on getting the puzzle that had doh.ie squirming

anyway :

6 + 7 = 13
9 * 8 = 72
13 * 72 = 936 - 25 = 911

nyom

Boro · 24-09-2004 04:48PM

1 2 7 9 10 50
target : 747

doh.ie · 27-09-2004 10:55AM

I could not be more angry at missing out on Boro's AND the evil of 911. Thought both were impossible. Must stop saying that.

Anyway...

(((10+2)*7)-1)*9=747

Coo. And 50 left over.
