Let's solve this step by step:

Expression:
$(-8 + 12 - 5 + 7) \times (11 - 13 - 7 - 2)$

Step 1: Simplify each part inside the parentheses.

First parentheses: $-8 + 12 - 5 + 7 = 6$

Second parentheses: $11 - 13 - 7 - 2 = -11$

Step 2: Multiply the results.

$6 \times (-11) = -66$

So, the value of the expression is: $-66$
