Algebraic structures consisting of 2 binary operations (e.g. ring) are subject to distributivity of one operation over the other.
Distributivity β¨ of over β¨:
left distributivity: a β¨ (b β¨ c) = (a β¨ b) β¨ (a β¨ c)
right distributivity: (b β¨ c) β¨ a = (b β¨ a) β¨ (c β¨ a)
(total) distributivity: left and right distributivity
Given a set and 2 binary operators and on , and
the operation is left-distributive over if:
the operation is right-distributive over if:
the operation is distributive over if: it is both left and right distributive
if is commutative, these 3 axioms are equivalent: left-distributive β‘ distributive β‘ right-distributive
Algebraic structures consisting of 2 binary operations (e.g. ring) are subject to distributivity of one operation over the other.
Given a set S
and 2 binary operators *
and +
on S
:
the operation *
is left-distributive over +
if
the operation *
is right-distributive over +
if
the operation *
is distributive over +
if it both left and right-distributive.
when *
is commutative, these 3 conditions are logically equivalent
a(b + c) = ab + ac
The Distributive Law does not work for division
