|Commutative Property of Addition
|| Changing the order in which you add does not change the sum.
|| a + b = b + a
|Commutative Property of Multiplication
||Changing the order in which you multiply numbers doesn't change the product.
||a x b = b x a
|Associative Property of Addition
||Changing the way the numbers are grouped does not change the sum.
||a + b ) + c = a + ( b + c )
|Associative Property of Multiplication
||Changing the way the numbers are grouped does not change the product.
||( a x b ) x c = a x ( b x c )
|Identity Property of Addition
||If you add zero to a number, you get the same number.
||a + 0 = a
|Identity Property of Multiplication
||If you multiply a number by 1, you get the same number
||a x 1 = a
|Inverse Property of Addition
||A number plus its opposite equals 0.
||a + ( – a ) = 0
|Inverse Property of Multiplication
||A number multiplied by its reciprocal equals 1.
||a / b = b or b / a
||a number outside parenthesis gets multiplied by every number inside parenthesis.
||a ( b + c ) = a b + a c
|Zero Property of Multiplication
||Any number multiplied by 0 equals 0
||a x 0 = 0
