Answer 2

To solve the expression, we'll perform the arithmetic operations step by step:

Step 1: Calculate the first term: 15.87 * (-1.09) Step 2: Calculate the second term: (-5.87) * (-1.09) Step 3: Add the results from Step 1 and Step 2.

Let's go through it:

Step 1: 15.87 * (-1.09) Multiply 15.87 by -1.09: 15.87 * (-1.09) = -17.3063 (rounded to 4 decimal places)

Step 2: (-5.87) * (-1.09) Multiply -5.87 by -1.09: (-5.87) * (-1.09) = 6.3973 (rounded to 4 decimal places)

Step 3: Add the results from Step 1 and Step 2: -17.3063 + 6.3973 = -10.909 (rounded to 3 decimal places)

The final result is approximately -10.909.
