On a cold winter day the temperature was - 1 below zero. At night the temperature be dropped 4. What was the final temperature

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

Step-by-step explanation:

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.
