Taking it to a more abstract level, would it ever make sense to add two temperatures together? For instance, we subtracted 8 degrees from 10 degrees to get the change in temperature of the day. However, what meaning would we get out of adding the temperature at the beginning of the day to the temperature at the end of the day? In general such an operation does not make any sense.
Actually this is not quite correct. if t1 ... t6 are temperatures then e.g.: (t1 + t2 + t3 + t4 + t5 + t6 ) / 6 is perfectly legal. regards Andy Little
