Write an integer for each word description.

a) seventy degrees above zero
b) fifty-two feet below sea level

The words above will indicate addition, and the words below indicate subtraction.

Seventy degrees above zero would be 70+0 which is 70.
Fifty-two feet below sea level would be 0-52, which is -52.
