I am going to tackle these as 2 separate questions.

Think about temperature. In summer it is hot and the temperature might be 20 degrees C or 80 degrees F (depending on how your country measures temperature)
Either way it is a normal number. However, I could put a + in front of the number and say it is +20 or +80 degrees.
(If there is no sign at all in front of a number then a positive is implied. That means that it is positive but the + sign might be invisable)
