Question

Adam and Eric went hiking at different times. Adam is currently 73 feet above sea level while Eric is just starting at 24 feet below sea level. What is the difference in their elevations?

Answer 1

Answer: The answer is 97

Explanation:

Since Adam is above sea level, the number 73 is positive. The number 24 would be negative since it's below sea level.

73 - ( -24) = 97

To check to make sure it's right we can do this:

-24 + 97 = 73

73 - 97 = -24
