Identity Property

The basic Number Properties (or laws) that apply to arithmetic operations are Commutative Property, Associative Property, Identity Property and Distributive Property.

Identity Properties

Identity Property (or Zero Property) of Addition

When you add 0 to any anumber, the sum is that number.

For example: 325 + 0 = 325.

Identity Property (or One Property) of Multiplication

When you multiply any number by 1, the product is that number.

For example: 65, 148 × 1 = 65, 148

Zero Property of Multiplication

The product of any number and 0 is 0

For example: 874 × 0 = 0

The following video explains : What is the identity property? How can you recognize it and name it when you see it? Why does is have the name it has? Why do mathematicians give everything, even something as seemingly simple as this a name?

The following video shows the commutative & identity properties of addition & multiplication.
