Question

A dolphin is swimming 4 feet below the surface of the water. the number -4 represents the dolphins position relative to the surface of the water. what position does the number 4 represent?
A. 0 feet below water
B. 4 feet above water
C. 8 feet below the water
D. 8 feet above the water

Answer 1

Answer: option B. 4 feet above water.

Explanation:

This is an example of the use of the integer numbers.

Integer numbers are positive, zero and negative numbers.

In this case, zero is used to represent the surface of the water. So, any positive number will be the position above water and any netative number will be the position below water. That is why, while - 4 represents the position of the dolphin below water, 4 represents the position 4 feet above water.
