Properties of multiplication operation on Z :
If a, b, and care three integers, then multiplication has the
following properties:
Closure: The product of any two integers is also an
integer. (a x b ? Z}
Commutative: a x b =b x a
Associative: (a x b)x c = a x (b x c)
Identity Element: The multiplicative identity is 1.
a x 1 =1 x a = a
Distribution property:
+a x (b c) = a x b + a x c
a x (b - c) = a x b – a x c
