#### Work Step by Step

RECALL:
Absolute value is defined as:
$|a| = a$ if $a \ge 0$
$|a| = -a$ if $a \lt 0$
Notice that:
(i) If the number is positive or zero, its absolute value is itself.
(ii) If the number is negative, its absolute value is its opposite, which is a positive number.
Thus, the absolute value of any real number is either positive or zero.
Therefore, the given statement is true.
