Answer:
He is 47 feet below the surface
Explanation:
The surface is zero, so the diver goes down -96 feet and then comes back up positive 49 feet, so we can write the math problem and solve:
-96 + 49
We are adding a negative and a positive so we do the following
a.) subtract the smaller integer from the larger
96 - 49 = 47
b.) use the sign from the larger integer (was negative) on the answer
-47
