multiplication properties of 0 and -1 0- for any number, n times the number zero is zero -1- for any non-zero n times -1 is going to be a negative number unless the number being multiplied is also negative, then the producct will be positive
Identity properties of addition and multiplication addition- tells us that zero added to any number is the number itself. Zero is called the "additive identity multiplication- tells us that the number 1 multiplied times any number gives the number itself.
