anyone?
Hi guys,
Been stuck on this problem for a few days now and still getting nowhere.
Let R be a ring such that Z ⊂ R ⊂ Q.(Z=integers, Q=rationals.) Show that R is a principal ideal domain.
So yeah, was trying to set up a euclidean function but just can't seem to find one that satisfies the conditions. Any suggestions would be greatly appreciated!
Thanks.
