What are the four addition properties?

Answer 1

Commutative property: When two numbers are added, the sum is the same regardless of the order of the addends.
For example a + b = b + a Associative Property: When three or more numbers are added, the sum is the same regardless of the order of addition.
For example (a + b) + c = a + (b + c) Additive Identity Property: The sum of any number and zero is the original number.
For example a + 0 = a. Distributive property: The sum of two numbers times a third number is equal to the sum of each addend times the third number. For example a x (b + c) = (a x b) + (a x c)
