Countdown numbers thread

[nqnln]

I saw this idea for a thread on another forum and it seemed to prove popular. It's based on Channel 4's Countdown, on their numbers game. So, I'll provide six numbers (chosen from 1-10, 25, 50, 75, 100) and the using numbers once (if at all) with addition, subtraction, multiplication or division, the target should be reached.

So here's a start, chosen randomly.

4, 6, 10, 3, 1, 75. Target: 346

The first to correctly solve (or if it is not solvable, the person who comes closest) can then post their own, and so on...

I can get 350:

3X10 = 300

+ 75 = 375

(4X6 = 24) - 24 = 351

-1 = 350

[sylvain74]

4*75=300
(3+1)*10=40
300+40+6=346

voila

Good work. The solver gets to put their own target at the end - helps keep the thread alive. But in lieu of that, here's another:

3, 9, 6, 2, 1, 50
Target: 771

[sylvain74]

damm... Found it again...

How do you generate new ones? Do you pick them at random? Do they have to be "solvable"?

[nqnln]

Yeah, I've just been picking numbers off the top of my head. I haven't checked this one - but come forth with your solution. And nah, they don't necessarily have to be solvable.

[sylvain74]

9-2=7
(6-1)*50=250
3*(250+7)=771

All right, let's try this (random) one:
3, 4, 7, 9, 50, 75
Target: 111

	3, 9, 6, 2, 1, 50 Target: 771

50*(6-1) = 250 + (9-2) = 257*3 = 771



Edit: Oh, sorry, I got called away just as I was about to press submit and sylvain74 beat me to it

(50+75) = 125 - (7+4+3) = 111

Dammit. I used to suffer that damned programme just for the numbers. Is there a 'Countdown Numbers Anonymous'?

7 9 4 6 9 8 target 984

Cool! Another number addict

(7*6)+(9*9) = 123
123*8= 984

10, 6, 3, 1, 4, 50 : 903

Noooooo! Stop now!!!!! I am still at work.

(6*3) * 50 + (4-1)

25 1 2 4 8 8 target 656

[sylvain74]

(2*25+4*8) * 8 = 82 * 8 = 656

Next is
3 7 7 7 8 75 target 602

	(2*25+4*8) * 8 = 82 * 8 = 656 Next is 3 7 7 7 8 75 target 602

(75*8)+3-(7/7) = 602

2 1 2 8 9 50 Target 744

	I can get 350: 3X10 = 300 + 75 = 375 (4X6 = 24) - 24 = 351 -1 = 350

I thought 3X10 was 30

Haven't managed any better than:

(50-(1+2)) * 2 * 8 - 9 = 743

[Wibble]

	Quote:	nqnln
	2 1 2 8 9 50 Target 744

50 x 2 => 100
100 - 9 => 91
91 + 2 => 93
93 x 8 => 744

Next: 1 3 5 5 7 75 Target 487

[sylvain74]

7*(75-5)-3 = 7 * 70 - 3 = 490 - 3 = 487

Next: 1, 4, 4, 6, 7, 50
Target: 997

Is this really something one can get hooked on, because if yes, I'll keep out of the game but it does look challenging !!!
