:I see what you are getting at, but you can have a negative number inside ||, it just translates to positive. You see this in just about ever math textbook. --[[User:DavidB4|David B]] ([[User talk:DavidB4|talk]]) 00:44, 15 April 2016 (EDT)

::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. [[User:MelH|MelH]] ([[User talk:MelH|talk]]) 02:01, 15 April 2016 (EDT)
