Answer:
-102.1
Step-by-step explanation:
When adding negative numbers, act as if you are subtracting that same number, but in its positive form.
So in reality, you could rewrite the equation as: (-7.8) - 12 - 82.3 = -102.1
282 feet is below the sea level it's mean -282. The highest elevation is 20,320 feet above the sea level.
20,320+(-282)=20,038
