Answer

True

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.
