Identity Property (Or Zero Property) Of Addition
When you add 0 to any number, 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
