Answer» Answer: Addition - There are four mathematical properties which involve addition. The properties are the commutative, associative, additive IDENTITY and distributive properties. Additive Identity Property: The sum of any number and zero is the original number. For example 5 + 0 = 5. Subtraction - Properties of Subtraction. Some properties of subtraction of whole numbers are: Property 1: If a and b are TWO whole numbers such that a > b or a = b, then a – b is a whole number. Multiplication - Properties of Multiplication. There are four properties involving multiplication that will HELP make problems easier to solve. They are the commutative, associative, multiplicative identity and distributive properties. Multiplicative Identity Property: The product of any number and one is that number. Division - There are four (4) basic properties of real numbers: namely; commutative, associative, distributive and identity. These properties only APPLY to the operations of addition and multiplication. That means subtraction and division do not have these properties built in. |
