an operation called a product is the multiplicative identity which is an element such that the residue class of number 1 is the multiplicative identity of the quotient

* The "Additive Identity" is 0
because 0 "Added" to any number equals itself.
* The "Multiplicative Identity" is 1
because 1 "Multiplied" by any number equals itself.
Memorize these two rules together, so if you forget you can compare again and remind yourself.
Both of these are important when you start using "inverses":
* The "Additive Inverse" is what you "add" to a number to get "0"
(5) + (-5) = 0
(-9) + (9) = 0
So it is always the opposite sign.
* The "Multiplicative Inverse" is what you "multiply" to get "1"
(5) x (1/5) = 1
(1/9) x (9) = 1
So it is always the reciprocal.

It is the number "1" since any number multiplied by 1 stays the same.
