Here's how I thought of it. LadyLorraine Send a noteboard - 10/05/2010 10:20:10 PM
1)2+3 normally is 5
to get 5 from 10, you multiply by 2

2)7+2 normally is 9
to get 63 from 9 you multiple by 7

*pattern recognition*

alter into mathematically neutral equations to check. Theoretically, if that is the pattern, every equation should fit.

1b) 2=x, 3=y. x+y=(x+y)*x!!!

Use other equation to check work (this is NOT guess and check. I did not arrive at the original answer by guessing)

2b) 7=y, 2=x. x+y=(x+y)*x!!

3b) 6+5=(6+5)*6 <---x+y=(x+y)*x (this is where I stopped)
4b) 8+4=(8+4)*8 <----x+y=(x+y)*x

Use projected solution to attempt to solve puzzle (again, this is not guess and check.)

9+7=(9+7)*9=144=correct


Strictly speaking, you are correct, it is not a "logical problem" (although I've seen PLENTY of published puzzles that are called logic problems that aren't.), but it is not merely "I'm going to randomly try shit until it works".

All that this problem required was the ability to break down the given "equations" and recognize the pattern when it danced in front of you like a naked marionette.

As mentioned, the "equation" presentation was a bit misleading, but I chose to present it how it was presented to me.

I despise these sorts of problems (spoiler) - 09/05/2010 09:38:41 PM 854 Views
that is correct (now no looking ahead, cheaters ) *NM* - 09/05/2010 09:43:35 PM 386 Views
Based on the view count I would say at least half the people have decided to cheat *NM* - 09/05/2010 09:52:42 PM 384 Views
Totally cheated - 10/05/2010 04:05:30 AM 723 Views

Oh yeah. - 09/05/2010 10:08:48 PM 786 Views
Not bad. Try this one. - 09/05/2010 10:21:42 PM 820 Views
i couldn't begin to tell you - 09/05/2010 10:29:09 PM 781 Views
That's going to bug me for ages now. - 09/05/2010 11:48:07 PM 735 Views
It is a lot harder, and you probably are . - 09/05/2010 11:53:26 PM 759 Views
You would need a good base in math to figure it out. *NM* - 10/05/2010 12:03:09 AM 405 Views
That... that was either brilliant or terrible. *NM* - 10/05/2010 12:10:12 AM 342 Views
It was a definite hint. - 10/05/2010 12:26:41 AM 760 Views
*NM* - 10/05/2010 12:25:03 AM 367 Views
Yeah, probably 99.9% of people won't get this, but it has less to do with patterns I think (spoiler) - 10/05/2010 12:21:06 AM 753 Views
This is correct. (spoiler obviously) - 10/05/2010 12:25:02 AM 729 Views
Right. I guess I might've found that eventually. - 10/05/2010 12:29:57 AM 759 Views
I never like base change ones, let me see if I can remember one... - 10/05/2010 01:28:06 AM 791 Views
To save confusion, anyone who gets that just give it in base 10 *NM* - 10/05/2010 01:52:45 AM 395 Views

Wow. I though the answer would be - 10/05/2010 09:22:15 PM 724 Views
Re: I hated this stuff in school, and always skipped it. - 10/05/2010 06:59:02 PM 764 Views
The one you got was poorly written. - 10/05/2010 01:37:26 AM 797 Views
I agree - 10/05/2010 01:59:15 AM 755 Views
Cake. - 10/05/2010 01:53:32 AM 742 Views
I cheated. - 10/05/2010 02:54:58 AM 787 Views
Heh, that's what I did too - 10/05/2010 05:20:47 PM 706 Views
Re: I might for Tim's. - 10/05/2010 06:55:12 PM 720 Views
Easy stuff - 10/05/2010 03:15:55 AM 1013 Views
Ths is not a logic problem. It's a puzzle. - 10/05/2010 02:33:19 PM 648 Views
Re: No no, there's a definite pattern. - 10/05/2010 06:50:01 PM 667 Views
ok, how do you analyze the problem? - 10/05/2010 08:08:21 PM 780 Views

Here's how I thought of it. - 10/05/2010 10:20:10 PM 766 Views
thanks for the explanation. and a reminder that I LOATHE that kind of stuff. *NM* - 10/05/2010 10:26:32 PM 408 Views
no problem - 10/05/2010 10:28:29 PM 750 Views
Thanks for the tip! *NM* - 10/05/2010 10:39:02 PM 379 Views
Re: Mine's fairly similar. - 10/05/2010 10:51:13 PM 736 Views
I got that. - 10/05/2010 11:07:11 PM 708 Views
yah yah i know i know - 11/05/2010 12:07:58 AM 773 Views
