Answer 2

Let's break down the expression step by step:

-25 - (-12) - [-3 - (-4)] - 20 - (-2)

First, deal with the innermost parentheses:

-25 - (-12) - [-3 + 4] - 20 - (-2) -25 + 12 - [1] - 20 + 2

Now, solve the expression inside the square brackets:

-25 + 12 - 1 - 20 + 2

Finally, perform the remaining arithmetic:

-12 - 1 - 20 + 2 -13 - 20 + 2 -33

So, the value of the expression is -33.
