#### Answer

Positive

#### Work Step by Step

RECALL:
$a-(-b)=a+(b)$
Thus,
$-16 -(-30) = -16+30$
The numbers being added have different signs. This means that to find their sum, their absolute values will be subtracted.
Since 30 has a bigger absolute value than $-16$, we know that the sum will have the same sign as $30$, which is positive.
Thus, $-16-(-30)$ will result in a positive number.
