::Sure.  But your confusing two things.  What you see is statements like | -3 | = 3.  That's different from, "for negative x, | -x | = ..."  The first is an example, and it's clear.  The second is confused.  The "for negative x" part says that x IS a negative number, like -3.  "| -x |" then becomes a positive number, like 3.  Examples with negative constants are fine.  Examples with variables that have been asserted to represent negative numbers, which are then negated, not fine.
