Explanation:

Just remember how the absolute value works: it always returns the positive version of the number it has inside itself. So, the absolute value of a positive number is the positive number itself, while the absolute value of a negative number is the positive version of that number. In formulas:

|24|=24, and |57|=57

So, let's see what's inside your absolute values: your equation is

|82||16|+|34||2+5|

Doing the sums and differences inside the absolute values gives

|6||5|+|1||7|

And now use what I said at the beginning: the absolute value of 6 is 6, the absolute value of 5 is 5, the absolute value of 1 is 1, and the absolute value of 7 is 7, and thus we have

65+17=17
