Answer 3

Let's break down the expression step by step:

1. Start with the innermost parentheses: -(-28). The negative sign before the parentheses changes the sign of the expression inside, so -(-28) becomes 28.

2. Next, evaluate the absolute value expressions: |-2+1|, |17|, and |-42|. The absolute value function returns the positive value of a number, so |-2+1| is equal to 1, |17| is equal to 17, and |-42| is equal to 42.

3. Now, substitute the absolute values with their respective values in the expression: 1 + 17 - 42 - 28.

4. Finally, perform the addition and subtraction from left to right: 1 + 17 equals 18, 18 - 42 equals -24, and -24 - 28 equals -52.

Therefore, the value of the expression ||-2+1|+17|-42|-(-28)| is -52.
