The set of natural numbers is .
The additive identity of a number, aa, is always 0 since . The set of all natural numbers lacks an additive identity because 0 is not a part of it.
The additive inverse of a number aa is −a since . The set of natural numbers does not include any negative numbers so for all natural numbers a, the additive inverse of −a would not be a natural number. In that case, the set lacks an additive inverse.
The multiplicative identity of a number aa is always 1 since . Since 1 is included in the set of the natural numbers, then the set does have a multiplicative identity does have a multiplicative identity.
The multiplicative inverse of a number aa is always since . If aa is a natural number not equal to 1, then is not a natural number. For example, would have a multiplicative inverse of which is not a natural number. The set of natural numbers then does not have a multiplicative inverse.
