Additve Identity Property
n + 0 = 0 + n = n
Additive Identity Property
The sum of a number and 0 is the original number
Multiplicative Identity Property
n x 1 = 1 x n = n
Multiplicative Identity Property
The product of a number and 1 is the original number
Additive Inverse Property
n + (-n) = 0
Additive Inverse Property
The sum of a number and its opposite is 0
Multiplicative Inverse Property
n x 1/n = 1 (n =/= 0)
Multiplicative Inverse Property
The product of a nonzero number and its reciprocal is 1
Closure Property
a + b E R
Closure Property
The sum or product of any two real numbers is a real number
Commutative Property
a + b = b + a
ab = ba
Commutative Property
You can add or multiply real numbers in any order without changing the result
Associative Property
(a + b) + c = a + (b + c)
(ab)c = a(bc)
Associative Property
The sum or product of three or more real numbers is the same regardless of the way the numbers are grouped
Distributive Property
a(b + c) = ab + ac
(b + c)a = ba + ca
Distributive Property
When you multiply a sum by a number, the result is the same whether you add and then multiply or whether you multiply each term by the number and then add the products
