Algebra: Law of Natural Numbers


Natural numbers refer to members of the set of positive integers or set of non-negative integers.

In Law of Natural Numbers, let x, y and z be any number, hence,

Law 1 - closure for addition: 
x + y

Law 2 - commutative law for addition: 
x + y = y + x

Law 3 - associative law for addition:
(x + y) + z = x + (y + z) = x + y + z

Law 4 - closure for multiplication:
x * y


Law 5 -  commutative law for multiplication:
x * y = y * x


Law 6 - associative law for multiplication:
x(y*z) = (x*y)z

Law 7 - distributive property of addition and multiplication:
x(y +z) = x*y + x*z
