Properties of Algebra
By: Will Bienkowski
Commutative Property
ExplanationThe commutative property
works for multiplication and addition. It states that switching the order of the numbers and variables will not change the sum or product.
Examples6+3=3+6 is for addition.
8·6=6·8 is for multiplication
Associative Property
Explanation
The associative property works for multiplication and addition. It states that that if you switch the grouping of numbers or variables the sum or product will stay the same.
Examples7+(6+2)=156+(7+2)=15
8(2·4)=642(8·4)=64
Identity Property
Explanation Example9+0=9
6·1=6
The identity property works for multiplication and addition. It states that anything added to zero or multiplied by one the result is that number.
Distributive Property
Explanation The distributive property
states that you can make hard and long problems easy and short.
Examples8·1048·100=8008·4=32800+32=832
Equality Property
ExplanationThe equality property states
that if you add or take away numbers from one side of the =,< or > you have to add or take the same number away from the other side.
Example3+b<9-3 -3b<6
Inverse Property
Explanation It states that addition and
subtraction can undo each other and multiplication and division can undo each other.
Examplea-a=0 and a+(-a)=0
a\a=1 and a·(-a)=1
