a+b = b+a
contoh :
matriks A =
1 2
8 0
matriks B =
2 6
1 7
maka a+b =
1 2 + 2 6 = 3 8
8 0 1 7 9 7
maka b+a=
2 6 + 1 2 = 3 8
1 7 8 0 9 7
maka dari contoh tersebut terlihat a+b = b+a
contoh :
matriks A =
1 2
8 0
matriks B =
2 6
1 7
maka a+b =
1 2 + 2 6 = 3 8
8 0 1 7 9 7
maka b+a=
2 6 + 1 2 = 3 8
1 7 8 0 87
