a X b = b X a
(a X b) X c = a X ( b X c )
misal a dan B bilangan bulat maka (a X B) juga bilangan bulat
a X 1 = a
maka 1 disebut identitas perkalian
a X (b + c) = a X b + a X c
a X (b - c) = a X b - a X c

Verified answer
Sifat Sifat Perkalian
a X b = b X a
(a X b) X c = a X ( b X c )
misal a dan B bilangan bulat maka (a X B) juga bilangan bulat
a X 1 = a
maka 1 disebut identitas perkalian
a X (b + c) = a X b + a X c
a X (b - c) = a X b - a X c
