The mathematical expression extracted from the image is:

$13 - (8 \cdot 14) - 13 + 5$

Let's solve it step by step:

1. First, evaluate the multiplication inside the parentheses: $8 \cdot 14 = 112$
2. Substitute the result back into the equation: $13 - 112 - 13 + 5$
3. Now, perform the operations from left to right: $13 - 112 = -99$ $-99 - 13 = -112$ $-112 + 5 = -107$

So, the result is $-107$.
