Addition Property
If a=b and c=d then a+c=b+d
Subtraction Property
If a=b and c=d then a-c=b-d
Multiplication Property
If a=b then ca=cb
Division Property
If a=b then cā 0 then a/c = b/c
Substitution Property
If a=b then either a or b may be substituted for the other in any equation (or inequality)
Reflexive Property
a=a
Symmetric Property
If a=b then b=a
Transitive Property
If a=b and b=c then a=c
Distributive Property
