1.3.2 Multiplication and Division of Real Numbers
SWBAT:1) Multiply and divide real numbers2) Connect and analyze properties for all basic operations (multiply, divide, add, subtract)

Commutative Property – Any Ordera b = b a2 (-3) = (-3) 2
Associative Property – Any Grouping(a b) c = a (b c)(2 (-3)) 5 = 2 ((-3) 5)
Identity Propertya 1 = a2 1 = 2
Inverse Property (reciprocal)a = 1
2 = 1a1

Property of Zero a 0 = 0 2 0 = 0
Property of -1 a -1 = -a 3 -1 = -3
-3 is called the opposite of 3

For any division or multiplication problem: Two numbers with the same sign result in a
postive answer◦ 2 3 = 6◦ -2 -3 = 6
Two numbers with different signes result in a negative answer◦ 2 -3 = -6◦ -2 3 = -6

For:◦ 3 5 = 3
Dividing by a number is the same as multiplying by a recipricol:
