Flashcards › Math: Properties and Identities

Reflexive Property exactly the same on both sides (mirror=reflection) Ex: let x = a number; x=x Multiplicative Identity if you multiply anything by 1 it equals what you started with Ex:let j = a number; 1j = j Multiplicative Property of Zero multiply anything by zero and you get zero Symmetric Property balanced on both sides (different than reflexive property) Ex:2+3=5, another example 9=3+5+1 Substitution Property replaces; simplifying the problem Additive Identity add zero to anything and it will be the same Ex: let z = a number; z+0=z Multiplicative Inverse any number multiplied by its inverse is 1 (inverse means opposite) Ex: (4)(1/4)=1 Commutative Property order does not matter (only works for addition and multiplication) Ex: 2+5=5+2 Associative Property group terms together in any way and solution will still be the same (only works for addition and multiplication) Ex: (2+5)+7=2+(5+7)
