Answer: 0
Explanation:
To evaluate the expression 2- -6|-17- -7| -8, we need to follow the order of operations, also known as PEMDAS.
First, let's simplify the expression inside the absolute value bars: |-17- -7|.
To do this, we subtract -7 from -17, which gives us -17 - (-7).
Remember that subtracting a negative number is the same as adding the positive number, so -17 - (-7) becomes -17 + 7.
Therefore, |-17- -7| simplifies to |-17 + 7|, which is equal to |-10|.
Next, we evaluate the expression inside the absolute value bars. Since -10 is negative, the absolute value of -10 is simply 10.
So, |-10| equals 10.
Now, let's substitute this value back into the original expression: 2-10-8.
We start from left to right, subtracting 10 from 2, which gives us -8.
Finally, we subtract 8 from -8, resulting in 0.
Therefore, the value of the expression 2- -6|-17- -7| -8 is 0.
