Commutative property:
For any two numbers a and b,
a + b = b + a
Associative property:
For any three numbers, a b and c,
a + (b + c) = a + b + c = (a + b) + c
Other properties, such as the existence of an identity and of an inverse depend on the set over which addition is defined. For example, the first two properties mentioned above are true for addition defined on the set of positive integers, N+. But this set does not include the additive identity (zero), nor the inverse of any element in the set. So the second pair of properties are not general but only when defined over specific sets.

What are the different properties of addition give example for each property?
properties of addition with example
Why are distributive property commutative property associate property and identity property called properties?
These are characteristics of the elements of algebraic structures, or algebraic sets. Each element in the set possesses these characteristics and that is why they are called properties.
Why is it subtraction and division are not included in the properties of each numbers?
Subtraction and addition are not properties of numbers themselves: they are operators that can be defined on sets of numbers.
What does identify the property mean?
There are different properties for each of the four basic operations. If you have to identify one, you just have to name it.
What is a property that states that multiplying a sum by a number is the same as multiplying each addend in the sum by the number and then adding the products?
The distributive property of multiplication over addition.
