Associative Property or Addition & Multiplication
(a+b)+c=a+(b+c)
ab)c=a(bc
Commutative Property of Addition & Multiplication
a+b=b+a
ab=ba
Identity Property of Addition & Multiplication
a+0=a, 0+a=a
a1=a, 1a=a
Inverse Property of Addition & Multiplication
a+(-a)=0
a*1/a=1, a doesn’t equal 0
Distributive Property
a(b+c) = ab+ac
Distributive Property for Subtraction
a(b-c)=ab-ac
Multiplication by 0
0*a=0
Multiplication by -1
-1*a=-a
Opposite of a Sum
-(a+b)=-a+(-b)
Opposite of a Difference
-(a-b)=b-a
Opposite of a Product
-(ab)=-ab=a(-b)
Opposite of an Opposite
-(-a)=a
Reflexive Property
a=a
Symmetric Property
If a=b, then b=a
Transitive Property
If a=b and b=c, then a=c
Addition Property
If a=b, then a+c=b+c
Subtraction Property
If a=b, then a-c=b-c
Multiplication Property
If a=b, then ac=bc
Division Property
If a=b and c doesn’t equal 0, then a/c=b/c
Substitution Property
If a=b, then b may be substituted for a in any expression to obtain an equivalent expression
