more mathematica, result 0 < n < negative number ???
I input the following to mathematica...

$m>n>0, \ \ \ p>q>0, \ \ \ q=p-\sqrt{2p^2-(m^2+2mn-n^2)},$
$pq(p^2-q^2)>2mn(m^2-n^2)$

and part of the result is

$0

with $m>0$, surely the RHS must be negative, so how can $n$ be greater than zero and less than a negative number ?
