Question 85561
Given:
.
{{{abs(-35)}}}
.
Evaluate this.
.
Those "bars" surrounding -35 are absolute value signs.  The purpose of absolute value signs
is to indicate that when the absolute value signs are removed, the quantity within them 
gets changed to a positive value regardless of the sign it had when it was inside the 
absolute value signs. [If the quantity inside the absolute value signs was plus, when the
absolute value signs are removed, it remains plus. However if the quantity in side the
absolute value signs was minus, when the absolute value signs are removed, it changes 
from minus to plus.]
.
In this problem you are told to evaluate {{{abs(-35)}}}. 
.
Recall the rule regarding the absolute value signs.  Remove the absolute value signs, but 
change the sign of the -35 so that it becomes +35 and +35 is the answer to this problem
.
Hope this helps you to understand the meaning of absolute value signs and how they work
on positive and negative quantities.
