Question

A scuba diver's first dive under

water was 45.32 feet and then
he swam 41.11 feet towards
the surface of the water?

Answer 1

-4.21 ft. below sea level

Explanation:

The expression is -45.32 + 41.11, and so you are basically just doing 45.32-41.11, but the answer will be negative.

45.32-41.11=4.21, but the answer is negative, so -4.21.
