TopNewestI 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.

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!

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! ;)

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

solutionto each line is shown. :)Log in to reply
