coba cek pake calculator deh....

1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321

1 x 9 + 2 = 11
12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11111
12345 x 9 + 6 = 111111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111111111
123456789 x 9 +10= 1111111111

9 x 9 + 7 = 88
98 x 9 + 6 = 888
987 x 9 + 5 = 8888
9876 x 9 + 4 = 88888
98765 x 9 + 3 = 888888
987654 x 9 + 2 = 8888888
9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888

Brilliant, isn't it?
And look at this symmetry:
1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111=123456789 87654321


12345679 x 9 x 1 = 111111111
12345679 x 9 x 2 = 222222222
12345679 x 9 x 3 = 333333333
12345679 x 9 x 4 = 444444444
12345679 x 9 x 5 = 555555555
12345679 x 9 x 6 = 666666666
12345679 x 9 x 7 = 777777777
12345679 x 9 x 8 = 888888888
12345679 x 9 x 9 = 999999999

ada lagi :
9 x 3 = 27 => 2+7 = 9
9 x 4 = 36 => 3+6 = 9
9 x 5 = 45 => 4+5 = 9
9 x 6 = 54 => 5+4 = 9

9 x 22 = 198 = 1+9+8 = 18 => 1+8 = 9
