O’Connor lives in North Dakota. When he leaves for work one wintry morning, the temperature is −4° C. By the time he comes home, the temperature has increased 25°. What is the temperature when he comes home?

21 degrees

Step-by-step explanation:

-4 + 25 = 21

or 25+(-4) = 21

essentially you begin the day below zero. and a 25 degree increase by end of day only means that you went from -4 to 0 and then to 21 (25 degrees was added to the negative starting number)

there would be 365 different 4 digit numbers
