The situation that describes opposite quantities that when combined would equal 0 is:
A diver was 30 feet below the surface and swam upward 30 feet. What is the change of elevation?
In this case, the diver's movement of going up 30 feet from -30 feet (below surface level) to 0 feet (at the surface) results in a change of elevation of 0 feet, effectively combining opposite quantities (30 feet up and 30 feet down).
