To calculate the expression, follow the order of operations (PEMDAS/BODMAS):

1. Perform the multiplication first.
2. Then, perform the addition.

Let's calculate step by step:

Step 1: Perform the multiplication 25.87 × (-2.09) = -54.0323 (rounded to four decimal places) (-7.87) × (-2.09) = 16.4483 (rounded to four decimal places)
