25 + 7 = 32
32 * 100 = 320
320 + 10 + 7 = 337

I'll go -

3, 7, 8, 9, 4, 25

Target: 272

feylya · 04-02-2004 2:41pm

(7+4)*25 - 3 = 272

2, 5, 7, 25, 50, 75 > 951

Imposter · 04-02-2004 2:57pm

(50 -5) * 7 = 315 + 2 * 75/25 = 951

10. 5, 7, 8, 3, 3 -> 596

PrecariousNuts · 04-02-2004 3:11pm

(7*8)+3 = 59
59*10 = 590+5+3 = 598

Close

ecksor · 04-02-2004 6:23pm

(7+8+5)*10*3 = 600 - 3 = 597

I think thats as close as it gets.

ecksor · 04-02-2004 8:16pm

PrecariousNuts would have been as close if he hadn't bothered to add that last 3.

Mixie · 04-02-2004 8:25pm

( ( ( 10 * 8 ) + 5 ) * 7 ) + ( 3 / 3 ) = 596

Ivan · 04-02-2004 9:43pm

Good job, however... post another one!

ecksor · 04-02-2004 9:46pm

I'll do it:

1 1 8 25 50 100

target: 819

( ( ( 100 - 1 ) * 8 ) + 25 ) + 1 = 818 is the closest i can get

Here's one:

10, 10, 7, 7, 5, 2 ----> 841

ykt0di9url7bc3 · 04-02-2004 10:02pm

( 5 + 7 ) * 7 = 84

10 * 10 = 100

84 * 100 = 840

(10+7)*5*10 = 850 - (7+2) = 841.

I'll leave my one up as the current challenge

This is a toughie because so FEW degrees of freedom
eg: 25=5*5 so only 3 different digits and two different primes (2,5)

How about people posting if they know if a solution exists.

PS.
5^4 = 625
5-4+1 =2
625/2 =312.5 - Ok not the closest

Argggg - the same two primes 2,5 - that ain't easy..

GuanYin · 05-02-2004 12:23am

I solved it eventually, but the game had gone on.

25-5 =20

20*4 = 80

(80-1) * 4 = 316

316-5 = 311

Its still ecksors challenge:

100-1=99
99*8= 792
792+25=817
817+1=818 - nearly there

I think we've had long enough. Maybe you should post the answer or else let Capt Midnight go!

p.pete · 05-02-2004 2:08pm

i've never seen this done on countdown but:

25/50 = 0.5
0.5 + 1 + 1 +100 = 102.5
102.5 * 8 = 820

still one out:mad:

Hehe, I couldn't find an answer either.

Mixie actually got the answer first, so ...

Capt'n Midnight · 05-02-2004 3:16pm

:d didn't see that - apologies Mixie

so we are still on 10, 10, 7, 7, 5, 2 ----> 841
three primes so should be a little easier.

ecksor · 05-02-2004 3:18pm

No, I already got that ...

(10+7)*5*10 - (7+2) = 841.

Capt'n Midnight · 05-02-2004 3:25pm

:d didn't see that - apologies ecksor
But you let your one stand - and AFAIK it's not easily solvable.

So its up to Mixie ?

Mixie · 05-02-2004 3:37pm

75, 9, 7, 7, 5, 1 ----> 797 (solveable)

Imposter · 05-02-2004 3:46pm

75 + 7 + 7 = 89 * 9 = 801 - 5 + 1 = 797

And:

3, 5, 7, 2, 10, 75 -> 654

Imposter · 05-02-2004 4:09pm

9*75 = 675
8-2 = 6 * 7 = 42

675 - 42 = 633

Imposter · 05-02-2004 4:10pm

1, 1, 2, 2, 3, 3 -> 999

Na seriously:

4, 4, 7, 9, 6, 10 -> 457
