There are four mathematical properties for
addition. They are the commutative property, associative
property, additive identity property, and distributive property.
Learn them and they will help you prepare for the GED Math test. 




Commutative Property of Addition

When two numbers are added, the sum of the addends are
the same, regardless of the order.
Example: 6 + 3 = 3 + 6
3xy + 16 = 16 + 3xy 

Associative Property of Addition

When three or more numbers are added, the sum of the
addends are the same, regardless of the order.
Example: 6 + 3 + 2 = 3 + 6 + 2
3xy + 16 + z = 16 + 3xy + z 

Additive
Identity Property of Addition

When a number is added to zero, the sum is the original
number.
Example: 7 + 0 = 7
3xy + 0 = 3xy 

Distributive Property of Addition

When a number (outside the parentheses) is multiplied
against two other addends, it is equal to the sum of
each addend multiplied against the number outside the
parentheses.
Example: 2 ( 4 + 8) = 2*4 + 2*8
