Term
Additive Identity Property |
|
Definition
a+0=a
any term added to 0 remains unchanged |
|
|
Term
Additive Inverse Property |
|
Definition
a+(-a)=0
when opposites are added, the result is always zero |
|
|
Term
Additive Property of Equality |
|
Definition
If a=b, then a+c=b+c
equality is maintained if you add the same amount to both sides of the equation |
|
|
Term
Associative Property of Addition |
|
Definition
a+(b+c)=(a+b)+c
if a sum contains terms that are grouped, then the terms can be grouped differently without affecting the result |
|
|
Term
Commutative Property of Addition and Multiplication |
|
Definition
a+b=b+a ab=ba
if two terms are added or multiplied, the order is reversible |
|
|
Term
Multiplicative Identity Property |
|
Definition
a*1=a
any term multiplied by one remains unchanged |
|
|
Term
Multiplicative Inverse Property |
|
Definition
(a/b)*(b/a)=1
when multiplying a term by its reciprocal, the result is always one |
|
|
Term
Multiplicative Property of Equality |
|
Definition
If a=b, then a*c=b*c
equality is maintained if you multiply both sides of an equation by the same amount |
|
|
Term
Associative Property of Multiplication |
|
Definition
a*(b*c)=(a*b)*c
if a product contains factors that are grouped, then the factors can be grouped differently without affecting the result. |
|
|
Term
Transitive Property of Equality |
|
Definition
If a=b and b=c, then a=c
if two terms (a and c) are both equal to a third term (b), then they must be equal to each other |
