While scuba diving, I noticed some cool sea life at 9 feet below sea level, which is -9 feet below the surface. I decided to dive downward 30 more feet to look at a ship wreck. Then, I decided to rise 18 feet to check out some beautiful fish. Where am I now located with respect to sea level in terms of feet?

Answer:

21 ft below sea level.

Step-by-step explanation:

if you go down 9 ft you are at 9 feet below sea level. If you go down 30 more feet you would be 39 feet below sea level. If you then rise up 18 feet you would be 21 feet below sea level.
