Properties of Real Numbers
Question | Answer |
---|---|
Commutative Property of Addition | a + b = b + a |
Commutative Property of Multiplication | a • b = b • a |
Associative Property of Addition | a + ( b + c ) = ( a + b ) + c |
Associative Property of Multiplication | 2 • ( 3 • 4 ) = ( 2 • 3 ) • 4 |
Distributive Property | a • ( b + c ) = a • b + a • c |
Additive Identity Property | a + 0 = a |
Multiplicative Identity Property | a • 1 = a |
Additive Inverse Property | a + ( -a ) = 0 |
Multiplicative Inverse Property | a( 1/a )= 1Note: a cannot = 0 |
Zero Property | a • 0 = 0 |
