There are two related identity properties: the additive identity and the multiplicative identity.
The additive identity property states that for x belonging to a set, there is an additive inverse in the set, which is denoted by -x such that x + (-x) = (-x) + x = 0, where 0 is the additive identity which also belongs to the set.
The multiplicative identity property states that for y belonging to a set, there is a multiplicative inverse in the set, which is denoted by 1/y or y-1 such that y * (1/y) = (1/y) + y = 1, where 1 is the multiplicative identity which also belongs to the set.
