Identity
An identity is a special kind of number. When you use an operation to combine an identity with another number, that number stays the same. Zero is called the additive identity, because adding zero to a number will not change it: the number stays the same.

0 + a = a = a + 0.
Since any number multiplied by one remains constant, the multiplicative identity is 1.

1 * a = a = a * 1.
