Question 89819
I think it's not a absolute value problem but i will try to help. Ok?
<p></p>
If n is negative {{{n-2}}} will be negative. Change n for a negative number for test, like -3:
{{{-3-2=-5}}}
<p></p>
If n is negative 2*n will be negative, like:
{{{2*(-3)=-6}}}
<p></p>
if n is negative and {{{sqrt(n^2)}}}( square root right?). Any number with exponent even is positive so, {{{sqrt(n^2)}}} will be the positive n:
{{{sqrt((-2)^2)=2}}}
<p></p>
{{{n/2}}} will be negative.
<p></p>
{{{2/n}}} will be negative.
<p></p>
Cheers.
