. A scuba diver went down 20 feet below the surface of the water. Then she dove down 3 more feet. Later, she rose 7 feet. What integer describes her depth?

Firstly she was 20 feet below the surface, then she dove down 3 more feet and then she dove up 7 feet, so:

-20 - 3 + 7 =
= -23 + 7 =
= -16 [feet]      (that's her depth)
