The expression should represent the change in temperature from noon to 1:00, which is +4 degrees Fahrenheit. Since the temperature at noon was -10 degrees Fahrenheit, adding 4 degrees will give a final temperature of -6 degrees Fahrenheit. Therefore, the correct expression is: -10 + 4 = -6. Choice E, (-10+4), represents the correct calculation for this expression.

The Temperature at Noon Is 10 Degrees Below Fahrenheit 0 −10−4-10-4−10−4
