Answer:
5
Step-by-step explanation:
Those straight lines that seem as brackets are not brackets...but they are a sign called the modulus,which mean that if the value inside has to be multiplied by a negative...so hence..onto the solution;
| 4(-2) - 8 | + | -1 - (-2)^2 | + 2(-2)^3
; | -8 - 8 | + | -1 -4 | + (-16)
; |-16| + |-5| -16
; 16 + 5 - 16
;Therefore answer, 5
