Answer 2

To find the value of the given expression, we'll perform the arithmetic operations step by step:

-326.98 + 25.35 + 0.63 - 1.2 + 129.1 + (-18.096) - 12.904 - (-117.1)

Step 1: Add all the positive numbers and the negative number in the parentheses: (-326.98) + 25.35 + 0.63 - 1.2 + 129.1 - 18.096 - 12.904 - (-117.1)

Step 2: Add the numbers: = -326.98 + 25.35 + 0.63 - 1.2 + 129.1 - 18.096 - 12.904 + 117.1

Step 3: Continue adding: = (-326.98 + 129.1 + 117.1) + (25.35 + 0.63 - 1.2 - 18.096 - 12.904)

Step 4: Add the numbers inside the parentheses first: = (-80.78) + (-6.216)

Step 5: Finally, add the two results together: = -80.78 - 6.216 = -86.996

So, the value of the expression is approximately -86.996.
