This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

I see "John Muradeli" here again, but is it really all the same letters of the name of the guy I used to know that came around here, or it just looks like it? What I do remember is that it sounded like the name of an olive oil company.
How is the order of division supposed to be resolved? I see 5 main expressions separated by 4 lines of division. If the lines were at least of different length, the order could be indicated.
That's true - but everyone in the building knows me, and I know them. And I know no-one can solve that - hence the 100$ price. Also, they could ask. In that case, I'd blab out the "standard method for arranging fractions," and I'd quote Wolfram|Alpha - a/b/c/d ... = a/b * c/d * ... .
In the original on Brilliant (which, 9 people have miraculously solved (or log-cheated)), I note that a/b/c/d = a/(b/(c/...)) - which, I think, luckily turns out to be the same thing.
Either way, no prize until the solution to each line is shown. :)

You're back!
I first saw this effect when I was 10 (I think) and it didn't take much time to figure out what was going on.
A cool effect nevertheless!
You are back !!
@Math Philic I see your friend's back:)
Spoilers: Don't read this : All the cards are different.

Don't give it away!
Took me a few tries to realize :O
I should be making a post anytime soon on the solution to the sum on the bottom of the fraction; I owe it to Mr. Mathopedia.
P.S. - the reward is for my school's students/staff ONLY! ;)
