Answer

$5$

Work Step by Step

Recall the following rule: $a-(-b)=a+b$. Thus, we obtain: $-14+19$ We can find the sum of a positive and a negative integer by subtracting the smaller absolute value from the larger absolute value and giving the result the sign of the original number that has the larger absolute value. Since $|19|>|-14|$, we can subtract $14$ from $19$, giving us $5$. Since the larger absolute value was originally positive, we give our result the positive sign: $5$
