Question 318278
<font face="Garamond" size="+2">


If *[tex \LARGE a\ <\ b] then *[tex \LARGE a^3\ <\ b^3]:  True.


If *[tex \LARGE a\ >\ b] and *[tex \LARGE c\ >\ d], then *[tex \LARGE c\ -\ a\ <\ d\ -\ b]


Sounds reasonable, no?


Let *[tex \LARGE a\ = 2], *[tex \LARGE b\ =\ 1], *[tex \LARGE c\ =\ 2], and *[tex \LARGE d\ =\ 1]


Then *[tex \LARGE 2\ -\ 2\ =\ 0\ =\ 1\ -\ 1]  NOT less than.
