# Summon vacuum

In Mathematical, the nap empties is the result of an addition of any number. Its numerical value is by convention equal to Zero. This fact is particularly useful in Mathématiques and in particular in Algèbre. A simple and well-known case is 0. has = 0. The multiplication of an unspecified number has by zero always gives like result zero, because we added zero copy of has , i.e. anything.

More generally, being given an operation of addition on a certain collection of objects, the empty sum is the result of an addition of any object of the unit. It is generally defined as being equal to the neutral element when this last exists for the operation given.

Many finds the sum empties easier to interpret than the Produit vacuum, i.e. the product without number (whose value is not zero, but a), because to add we can start from anything which is represented by zero and add possible terms.
