You can put this solution on YOUR website! Maybe you don't understand absolute value. If the number between the two
bars|| is positive or zero, just erase the bars. If the number between
the bars is negative, erase the bars AND the negative sign, making it a
positive number.
Three of them -1, 7, and -7 are already simplified as a positive or negative
number.
Only two of them, |-6| and |8|, need to be simplified. So we simplify them:
|-6|=6,
|8|=8
We draw a number line, like this:
--------------------------------------------------------
-9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9
Then we put them all on the number line
-------o-----------------o--------------------o--o--o---
-9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9
| | | |
-7 -1 |-6| 7 |8|
Then we list them as they appear left to right
-7, -1, |-6|, 7, |8|
