Suppose a deep sea diver dives from the surface to 85 feet below the surface. He then dives down 14 more feet. The diver's depth is represented by the sum - 85+ (-14). Find and interpret the sum to
describe the diver's present depth.
Find the sum.
- 85+ (-14) =
What is the diver's present depth?
O-99 feet below the surface
- 71 feet below the surface
O 71 feet below the surface
O 99 feet below the surface
