commutative property of addition
the order in which you add two numbers does not change the sum. eg: a+b=b+a

the way you group three numbers in a sum does not change the sum. eg: (a+b)+c=a+(b+c)
Identity property of addition
the sum of a number and 0 is the number. eg: a+0=a
inverse property of addition

associative property of multiplication
the way you group three numbers in a product does not change the product. eg: (a•b)•c=a•(b•c)
identity property of multiplication
the product of a number and 1 is that number
