When 0 is used as a number, it represents the quantity of nothing or no value. It is often referred to as the "null" or "empty" value. In mathematics, 0 is the additive identity, meaning that when it is added to any number, the result is that same number. It is also the starting point for the number line and serves as a reference point for positive and negative numbers.
