The numbers in these -> | brackets indicate absolute number which means the numbers between them are always end up positive
Just follow regular BEDMAS/PEDMAS:
|-19+(9/3)| - |14-(22/9)|
|-19+3| - |14-2.444|
|-16| - |11.556|
Then at the end make sure the numbers are all positive:
|16| - |11.556| OR just 16 - 11.556
= 4.444
