Well I have to send this problem to a website and I think I have to make some calcules... I know that my goal is to understand how to solve it and not to receive the solution but is there anyone who can solve it so I can earn the maximum points? Thanks.

In every top of a regular polygon with 2n tops there is written an integer number so the numbers written in two neighboring tops always differ by 1 ( the numbers are consecutive ) The numbers which are bigger than both of their neighbors are called ”mountains” and those which are smaller than...

Thanks everyone but please understand that I'm only 14. I'll try to figure it out somehow.

Hahahaha why not to use the best method? (if I would know which it is)

What should I reply? All of you have different opinions... it's hard for me to understand something.

But how to prove that?

We have a,b,c different complex numbers so (a+b)^3 = (b+c)^3 = (c+a)^3 Show that a^3 = b^3 = c^3 From the first equality I reached a^3 - c^3 + 3b(a-c)(a+b+c) = 0 How a is different from c => a-c is different from 0 How do I show that a^3 - c^3 = 0?

Thanks anyway man, a very good math guy helped me on other forum with a modulo n solve. It was the best I`ve ever seen. It is solved now, but thanks!

You didn't understand. We say that a number x = {x} + [x] http://en.wikipedia.org/wiki/Fractional_part (a,n) = 1 that means the greatest common factor Ex: (2, 3)=1 (23, 29)=1 (14, 19)=1 Hope this helps but I think you know physics better because this notions are learned in middle school...

Hi everyone! How to solve this: S(n) = { (a+b)/n } + { (2a+b)/n } + { (3a+b)/n } + ... + { (na+b)/n } where {x} represents fractional part of x. a,b,n are natural non-null numbers and (a,n)=1. I don`t need only an answer, i need a good solution. Thanks!
