Why are the complex numbers unordered?

first post on here!




I have been learning about complex numbers, and how they do not satisfy the trichotomy like real numbers do.



For example, there is no way to say i<3, i>3, or i=3.



But consider this: If $xSo let x=1 and y=9.
Then 1<9, so 1<9. In other words, i<3.



Can someone explain the flaw in this reasoning?




I imagine that it has something to do with 1 not being real, and so the x,y statement doesn't apply, but I can't think of a way to say why it doesn't apply. It seems like it should, since -1 is real, even if its square root is not.



Thanks!
