If these numbers represent elevations in meters, which is the farthest away from sea level?

Option (1)

Step-by-step explanation:

Minus notation of the elevations from the sea level represents the distance below the sea level and positive notation represents the elevations above the sea level.

+7 → 7 meters above the sea level

-3 → 3 meters below the sea level

→ 0.5 meters above the sea level

-0.8 → 0.8 meters below the sea level

+0.8 → 0.8 meters above the sea level

→ 0.1 meters below the sea level

-2 → 2 meters below the sea level

Therefore, +7 meters above the sea level will be the farthest point from the sea level.

Option (1) will be the answer.
