Commutative Property

• Commutative Property of Addition--changing the
  order in which you add does not change the sum.

So,
More Examples

• Commutative Property of Multiplication--changing
  the order in which you multiply numbers doesnt
  change the product.

So,
More Examples

Associative Property

• Associative Property of Addition--changing the
  way the numbers are grouped does not change the
  sum.

Add parenthesis to show Associative Property

6
Identity Property

• Identity Property of Addition--if you add zero to
  a number, you get the same number!

0 is called the identity of addition!!
7
Identity Property

• Identity Property of Multiplication--if you
  multiply a number by 1, you get the same number!

1 is called the identity of multiplication!!
8
Zero Property (of Multiplication)

• Any number multiplied by 0 equals 0!

9
Inverse Property

• Inverse Property of Multiplication--a number
  multiplied by its reciprocal equals 1.

10
Inverse Property

• Additive Inverse Property--a number plus its
  opposite equals 0.

11
Distributive Property

• A number outside parenthesis gets multiplied by
  every number inside parenthesis.
