###
Closure Property

a + b E R

###
Closure Property

###
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
