The Additive Identity

Before we explore the additive identity, let's first establish what the Identity Property is!

The Identity property of an OPERATION is the unique number which when used with the operation on another number does NOT CHANGE that number!

The ADDITIVE IDENTITY for EVERY number is Zero (0).

Why?  Because if you ADD Zero (0) to any number, that number does not change.

The Additive Identity is only one of the Properties of Arithmetic your student needs to know.
