### Multiplicative Identity Property

The product of a number and 1 is the original number

n + (-n) = 0

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

a + b E R

### Closure Property

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

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
