untuk setiap a dan b bilangan bulat berlaku a+b maupun b+a menghasilkan bilangan bulat
Contoh
2 dan -5 bilangan bulat, maka 2 +(-5) =-3 , -3 merupakan bilangan bulat
3
untuk setiap a dan b bilangan bulat berlaku a+b = b+a
Contoh
4 dan 7, maka 4+7=7+4
11 = 11
4
a,b,c bilangan bulat maka berlaku (a+b)+c =a+(b+c)
Contoh
4,7 dan -10
(4+7)+(-10) = 4+(7+(-10)
11 +(-10) = 4 +(-3)
11 = 11
