2 votes 2 votes z+= 1,2,3,4,5,6.... if orderd then 1 should be related to 2 and 2 should be related to 3 so on in ordered fashion. so, only one possibility is 1<=2<=3<=4..... similarly for z- we have -1>= -2>= -3....... hence ans. should be (z+,<=) and z-(>=). _sonu answered Jan 28, 2019 _sonu comment Share Follow See all 2 Comments See all 2 2 Comments reply jatin khachane 1 commented Jan 29, 2019 reply Follow Share 👍 @sonu 0 votes 0 votes Raj Kumar 7 commented Jan 29, 2019 reply Follow Share I think answer is only (Z+, <=) and least element in ordering is 0. But in case of (Z-, >=) there is no any fixed least element in this ordering. If i am wrong explain this 0 votes 0 votes Please log in or register to add a comment.
