I can see how desperate you are to make it look like I did not know
what I was talking about.
But you kid never seem to learn softly and prefer it the hard way.
[Free lesson for "Dirt fan the mortal"]
In Algebra we use variables.
In the expressions you posted up there (x) is being used as a
variable.
Excluding the sign from the variable implies that your concept of a
variable does not tolerate negative values.
Please answer by YES or NO.
Are you suggesting that an algebraic variable may not acquire a
negative value internal to the symbolic representation?

|_| Yes?
|_| No?

Your answer please.
