(18,2 - 76) • (56 + 7,5) =0

Let's evaluate the expression step by step.

1. Calculate the first part: \[ 18.2 - 76 = -57.8 \]

2. Calculate the second part: \[ 56 + 7.5 = 63.5 \]

3. Now, multiply the two results: \[ (-57.8) \cdot (63.5) = -3678.3 \]

So the final result of the expression \((18.2 - 76) \cdot (56 + 7.5)\) is:

\[ \boxed{-3678.3} \]
