A submarine was operating 234 feet below the surface of the ocean. Then, an underwater current caused the submarine to rise 112 feet.

To find the position of the submarine relative to the surface of the ocean after it rises 112 feet, we start with its initial depth of 234 feet below the surface, which we can express as -234 feet (since below the surface is negative).

The submarine then rises 112 feet, which we can express as +112 feet.

We can calculate the new position as follows:

\[
-234 + 112 = -122
\]

Thus, the position of the submarine relative to the surface of the ocean is 122 feet below the surface.
