Hello, and thank you for asking your question here on brainly.
When we have either a positive or negative number in the " | | " signs, that means its in absolute value, or positive form. Now we have this. (v v v)
-8 - 3 + 5 - 11
Do order of operations, so we do -8 - 3 first.
-11 + 5 - 11
Do the addition now.
-11 + 5 = -6
-6 - 11 is what we have now.
-6 - 11 = -17
-17 is your final answer.
Hope this helps! ☺♥
