Is it standard to write $2>1>0$ or we should write $2>1$ and $1>0$?

First is shorthand for second. – zkutch Oct 04 '20 at 01:43

It's unambiguous; I do it and I think it's fine. – Qiaochu Yuan Oct 04 '20 at 01:43

It is indeed fine. But you should be aware that in practice, the same information is more often conveyed by writing $0<1<2$. – Lubin Oct 04 '20 at 02:25
There is no ambiguity in $0>1>2.$ (On the other hand, $p⇒q⇒r$ might mean either $$p⇒(q⇒r)$$ or $$(p⇒q)⇒r$$ or $$(p⇒q)\text{ and }(q⇒r),$$ no pair of which is logically equivalent.) – ryang Jul 09 '22 at 17:52
