Mathematical Properties
Associative Property - grouping of numbers does not change the sum or product-moving the parentheses has no effect on the answer Commutative Property - the position of numbers does not change the sum or product changing the order of numbers has no effect on the answer Addition Identity - any number plus zero equals the same number Multiplication Identity - any number mulitplied by 1 equals the same number Distributive Property - Multiply the number on the outside of ( ) by each number on the inside of the ( ), then add the products --- "share the love" Property of Zero - any number multiplied by zero equals zero Inverse Operations - opposite mathematical operations and - or x and / Symmetric Property of Equality - both sides of an equation must equal the same value - "whatever you do to one side of an equation, you must do to the other" Extension of Place Value - using the basic facts and annexing zeros 2 x 6 = 12 200 x 6 = 1200 Reciprocal - any number multiplied times its reciprocal will equal 1 3 x 1/3 = 1 3 and 1/3 are reciprocals |
