Lesson 12Properties of Real Numbers

Obj SWBAT

Justify manipulations of expressions using the properties of real numbers

Associative Property

The grouping of the numbers does not change the sum or the product

Additiona + (b + c) = (a + b) + c

Multiplication(amiddotb)middotc = amiddot(bmiddotc)

Hint The different GROUPS of numbers can all associate with each otherhellipthey are all

friends

Commutative Property

The order of the numbers does not change the sum or the product

Addition

a + b = b + a

Multiplication

amiddotb = bmiddotaNo matter how you flip

themhellipthe answer is always the same

Distributive Property

The term outside the parentheses can be multiplied by all the terms on the

inside of the parentheses

a(b + c) = (amiddotb) + (amiddotc)

a(b ndash c) = (amiddotb) ndash (amiddotc)

You distribute so that everyone gets an equal turnhellipget it

Identity Property of Addition

The sum of a number and zero is the number

a + 0 = a

Addition

+

Identity Property of Multiplication

The product of a number and one is the number

a 1 = a

Inverse Property of Addition

The sum of a number and its opposite is zero

-a + a =0

Inverse Property of Multiplication

The product of a number and its reciprocal is one

11

a

a 0a

When might you use this property in solving equations

Zero Product Property

The product of a number and zero is zero

a 0 = 0

Closure Property

The sum or product of any two real numbers is a unique real number

(If you add or multiply any two real numbers the sum or product is one

and only one real number)

a + b = real numbera b = real number
