Answer 2

To solve the given expression, let's write it down in a column and perform the calculations step by step:

3.9
2.8
6.89
5.7
0.807
13.5
123.4
-59.2
12.1
-3.9
61.04
-4.592

Now, let's calculate the sum of these numbers:

3.9
2.8
6.89
5.7
0.807
13.5
123.4
-59.2
12.1
-3.9
61.04
-4.592
------

Adding all the numbers together, we get:

3.9
2.8
6.89
5.7
0.807
13.5
123.4
-59.2
12.1
-3.9
61.04
-4.592
------
161.847

Therefore, the result of the expression 3.9 + 2.8 + 6.89 + 5.7 + 0.807 + 13.5 + 123.4 - 59.2 + 12.1 - 3.9 + 61.04 - 4.592 is 161.847.
