What are the properties of addition and it's example

Properties of addition and it's example. Please answer. And I hope it's right answer, I need to pass my assignment on June 13,2013.

'' I need the answer please, and the example like zero property ( 8+0=8 )''

Thank You for your answers! I appreciate your help! :)

Please add a comment if you have any answers. I gave a example like Zero Property ( 30+0 ). Like what I said. You don't need a to give Zero Property cause I already know about it. I need Identity Property and the example, One Property and the example, Commutative Property and of course it's example. Thank You for your cooperation! And bless you all! I appreciate your help!

The three properties of addition are the commutative, associative and identity and here are the examples for each:

3+7=7+3 commutative (You can add two numbers in any order.)

17 + (9+3) = (17 + 9) + 3 (You can change the groupings of addends.)

10+0=10 identity (Any numbers plus zero equals that number.)

The "Zero Property" is actually called the Additive Identity Property. The additive identity is the unique number which, when added to any other number returns a sum which is the other number. 0 is the additive identity.

The Additive Inverse Property is that each nonzero number has a unique number which, when added to the number will return a sum of zero. (A more mathematical way to say this is that it will return a sum which is the additive identity.)

Examples: 23 + (-23) = 0     -(3/4) + (3/4) = 0    √3 +(-√3) = 0     - x2 + x2 = 0

The Commutative Property of Addition is that when two numbers are added together they will produce the same sum, regardless of the order of the two numbers.

Examples: 28.3 + (-12.7) = 15.6,  -12.7 + 28.3 = 15.6

                (1/3) + (3/4) = (13/12),  (3/4) + (1/3) = (13/12)

 

What you are calling the 1 Property is the Multiplicative Property of Identity. It is not a property of addition. 1 is the identity for multiplication, just like 0 is the identity for addtion.
