Answer:
-1 + -4 = -5 below zero....If the temperature is -1 + 4 the temperature would be 3 degrees (-1+4=3)

If the temperature is -1 + -4 = -5 below zero (adding two negatives equal a negative number).
If the temperate is -1 + 4 = 3 (+4-1=3) The number is positive because it is larger than the negative number.
