Answer 1

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
