211 + (13/13) + (99/99) - 2 + 11 - 8 = 214

not quite 0 = 0 but still a kinda trivial solution involving the 13/13 and 99/99.  nowhere near as impressive as that WW2 era OR-2/US-101 photo!

Thanks for the props on that; it took me quite awhile to figure that one out.


Anyway, here's another which is a little more difficult.  I assume these two signs function effectively as one assembly...

I think that's reasonable, not the extremely anal rules on the RSM site which apparently allowed a submission to hinge on a single structural support bar.  Lame.

I know.  This is totally unfair: I teach math, so those mental muscles have stayed strong.

No takers?  It isn't that horrifically hard...

sqrt(197-97)=(26-22)+(68-62)

Not complicated when you look at it. The fact that 197-97 = 100 and all the numbers on top are even is a glaring nudge in the right direction.


This one should be easier:

That's 1, 7, 87, and 95. Go!


If you always take the same road, you will never see anything new.

(87+7) = (95-1)



One of the numbers does not get used - and that number is not a route number

You can use them all:  29 + 81 = 66 + 65 + 1 - (10 + 12).  Those are the only numbers on the main assembly.

Here's a really hard one also involving US 10 and 12:



O.k., I'm joking.  I'm still looking for a good new photo.

All right, here's another.  Try to find a solution where you aren't just balancing the identical numbers, there's a more clever equation.

My first go at one of these...

120/20 - (16-14) = 120/(16+14)


Unfortunately, I don't have access to any road photos right now as I'm away from my home computer.  I invite anyone to post a new photo in my stead.

Good answer, and thanks for sticking with my rules for it!

I'll look for another to post, but it takes awhile, as I have to make sure there is an answer first.

Here's another relatively simple one from I-90 in the Keystone State:




Government would be tolerable if not for politicians and bureaucrats.

I'd solve it, but I can't do math in Clearview. :confused:

Here's another tough one:

All Clearview jokes aside, 2 x 9 = 18

No answer yet.  We are only using the four numbers (9, 57, 301, 501) on the arm, right?  I can solve it using the background shields and speed limit as well, but using any numbers in the background wouldn't be following the rules.

I've got a good one to follow this photo ready to go, but I want to solve this one first.

Yeah, just the numbers on the arm.

You'll have to show me your solution, NJRoadhorse; I'm stumped!

Here's that photo I was promising.  The WA 12 is an error; it should be US 12.


Duke87

Easy enough. 25+5/5+12-14=44-20

The mast arm one, however, is driving me crazy.
If you always take the same road, you will never see anything new.

xonhulu

Good job.  I'm still stumped on the mast arm problem, too.

Glad this thread isn't dead.  Here's one for someone to crack:

Cool game...here's one solution:
sqrt[37+sqrt(25)-26] = 52/26+2

I'm still getting pictures set up for future use, so someone else can go ahead and post up a new one if they wish.

So you need to have a number present in the previous photo then?  OK, how about this one? 
(Sorry for the blurry night photo)



(26-1)/((25² + 20²)-1000) = 187-186

Here's a wicked simple one:
"Officer, I'm always careful to drive the speed limit no matter where I am and that's what I was doin'." Said "No, you weren't," she said, "Yes, I was." He said, "Madam, I just clocked you at 22 MPH," and she said "That's the speed limit," he said "No ma'am, that's the route numbah!"  - Gary Crocker
