@Mathemagician1234: He could just be having an off day. His other questions lead to believe he's ready.

comment Trouble showing the addition of the fractional parts are a group.
Ok thanks! Yeah, I wrote it backward mostly because it is a comment and I wanted to keep it compact, but still illustrate the crux of my point. I have it better written out in my notebook. Thanks!

comment Trouble showing the addition of the fractional parts are a group.
Ok, I think I get it. As for the second part, I talk about it with Cameron. As for the first part, interpreting the operation as you say I should I get: $([x] + [y]) + [z] = [x] + ([y] + [z])$ Which implies: $[x+y] + [z] = [x] + [y+z]$ Which implies: $[(x+y) + z] = [x + (y + z)]$ Which using additions associative-ness gives: $[x+y+z] = [x+y+z]$ Correct?

@CameronWilliams: Ok, I guess that is there to help with the identity element confusion I initially had. That should be simple enough: $x-x' = n$, $y-y' = k$ $x + y - x' - y' = x - x' + y - y' = n + k$. Thanks for clarifying that.

comment What does non-zero integer mean?
-1, -2, 1, 3, 5, 7 are all examples of non-zero integers. 0 however is zero and not non-zero...
