Answer 2

Let's calculate the expression step by step:

(0.123 + 4.56 + 78.9) * (9.8 – 8.7 + 7.6 – 6.5 + 5.4 - 4.3 + 3.2 - 2.1 + 1.1 – 5.5)

First, let's simplify the addition and subtraction inside the parentheses:

(0.123 + 4.56 + 78.9) * (9.8 + 7.6 + 5.4 + 3.2 + 1.1 - 8.7 - 6.5 - 4.3 - 2.1 - 5.5)

Next, let's calculate the values inside the parentheses:

(83.583) * (9.8 + 7.6 + 5.4 + 3.2 + 1.1 - 8.7 - 6.5 - 4.3 - 2.1 - 5.5)

(83.583) * (15.8 + 9.9 - 13.6)

(83.583) * (12.1)

Now, let's multiply the two values:

(83.583) * (12.1) = 1010.3243

Finally, let's round the result to two decimal places as specified in the question:

1010.3243 ≈ 1010.32

Therefore, the result of the expression (0.123 + 4.56 + 78.9) * (9.8 – 8.7 + 7.6 – 6.5 + 5.4 - 4.3 + 3.2 - 2.1 + 1.1 – 5.5) is approximately 1010.32.
