The position of a swimmer below sea level is represented by negative 5 meters. The diver descends an additional 3 meters below sea level. Which expression describes the new position of the diver?

The swimmer starts at negative 5 meters, represented by −5. Descending an additional 3 meters means moving farther below sea level, so add −3: −5 + (−3). This is the expression “negative 5 plus negative 3.”
