Properties of operation
Term | Definition |
---|---|
Communicative property of addition | The order in which you add numbers can be changed without changing the sum. a+b=b+a |
Commutative Property of Multiplication | The order in which you multiply numbers can be changed and the product will not be changed. ah=ha |
Associative Property of Addition | Changing the grouping of the addends will not change the sum. a + (b + c ) = (a + b)+c |
Associative property of multiplication | Changing the grouping of factors will not change the product.a ∙ (b ∙ c ) = (a ∙ b ) ∙ c |
Distributive property | Multiplying a sum by a number is equal to the sum of the number multiplied by each of the addends.a (b + c ) = a (b ) + a (c) |
Identity Property of Addition | Adding zero to any number does not change the number. a+0 = a |
Identity Property of Multiplication | Multiplying any number by 1 does not change the number. a ∙ 1 = a |
Inverse Property of Addition | If you add a number and its opposite, the answer will always be zero. a+ (-a) =0 |
Inverse property of multiplication | If you multiply any number by its multiplicative inverse (reciprocal) the answer is always 1. |
Property of equality | what you do to one side of an equation, you must do to the other side. |
