Descending: subtraction

Rises: Addition

The diver descends 100ft: Position -100 (the 0 is the sea level)

Then rises 28: Add 28 to the previous position: Position -72


-100+28=-72

...before descending another 33: Subtract 33 to the previous position:


-72-33=-105

Then, the final position is -105ft (105 ft under the sea level)
