11. Calculate the following: \( \begin{aligned} \text { Example: } & -14-(-20) \\ & =-14+20 \\ & =6\end{aligned} \)

To solve \( -14 - (-20) \), we begin by rewriting the problem: \( -14 + 20 \). This is because subtracting a negative is the same as adding its positive. Now we simply perform the addition: \( -14 + 20 = 6 \). Thus, the answer is \( 6 \). Another example of a similar operation is \( 5 - (-8) \). First, we rewrite it as \( 5 + 8 \). Adding these together gives us \( 5 + 8 = 13 \). So for this problem, the answer is \( 13 \).
