Answer 2

To simplify the expression, let's perform the calculations step by step:

11.8 - (-2.6 + 1.8) * 3.6 - (8.7 - 5.4) - 7.6 + (-5.21 + 17.9 - 101)

First, let's simplify the inner parentheses:

= 11.8 - (-0.8) * 3.6 - 3.3 - 7.6 + (12.59 - 101)

Next, let's perform the multiplications:

= 11.8 + 0.8 * 3.6 - 3.3 - 7.6 + (12.59 - 101)

= 11.8 + 2.88 - 3.3 - 7.6 + (12.59 - 101)

= 11.8 + 2.88 - 3.3 - 7.6 + (-88.41)

Now, let's perform the additions and subtractions:

= (11.8 + 2.88 - 3.3 - 7.6) - 88.41

= 4.78 - 88.41

= -83.63

Therefore, the result of the expression 11.8 - (-2.6 + 1.8) * 3.6 - (8.7 - 5.4) - 7.6 + (-5.21 + 17.9 - 101) is approximately -83.63.
