ok so you were saying 45 is the same as -5 modulo 50? how does that divide ? ? i think i'll try to just look up stuff online.

ok, my head hurts. i don't think we covered modulo arithmetic in details. that might have been in a previous class but I've forgotten about it. maybe i will go and revisit it.

yes i was saying that <5> means an order of 10 since there's {0, 5, 10, ..45} 10 elements in the set before it reaches the identity- which is 50. so at 50 it would go back to 5. but I'm just not really suer how u determine which elements are duplications of one another like how 45 and 15 is the...

i'm kind of confused how u got 45 to be -5 modulo 50?

<x> is suppose to mean the order of the element, so <5> means any elements with order 5? so.. in terms of group addition, that would mean if x = 5, then it gets added five times before it becomes the identity? sorry lol I'm so bad at this

<15> = {0, 15, 30, 45} <45> = {0, 45} ??

:/ then i don't really see any other element that is remotely similar except maybe 15?

hmm.. 0?

i'd say no to that. but i don't really know how to tell which elements are reduplicates of each other. just that <10> would be {0, 10, 20 etc.}

I entered all the integers in the set like this: 0, 5, 10 etc. to 45. i added a picture below. imagine the number going up to 45.

because i entered the answer in webwork and it says not correct :'( I'm so confuzzled.

Homework Statement Find all elements x in Z50 such that <x> = <5> Homework Equations none really The Attempt at a Solution I thought <5> would be equal to {0, 5, 10, 15 ... 45} but that doesn't seem to be correct... can anyone tell me what I'm doing wrong?
