MARILAH KITA BERMAIN MATEMATIKA
0 x 9 + 0 = 0
1 x 9 + 1 = 10
12 x 9 + 2 = 110
123 x 9 + 3 = 1110
1234 x 9 + 4 = 11110
12345 x 9 + 5 = 111110
123456 x 9 + 6 = 1111110
1234567 x 9 + 7 = 11111110
12345678 x 9 + 8 = 111111110
123456789 x 9 + 9 = 1111111110


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 = 12345678987654321


Another Magic of Math

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



Then... Check this out ...

1 x 18 + 1 = 19
12 x 18 + 2 = 218
123 x 18 + 3 = 2217
1234 x 18 + 4 = 22216
12345 x 18 + 5 = 222215
123456 x 18 + 6 = 2222214
1234567 x 18 + 7 = 22222213
12345678 x 18 + 8 = 222222212
123456789 x 18 + 9 = 2222222211


Coba yg ini....
123456789 + 987654321 = 1111111110
1 x 142857 = 142857 (angka sama)
2 x 142857 = 285714 (angka sama beda urutan)
3 x 142857 = 428571 (angka sama beda ururan)
4 x 142857 = 571428 (angka sama beda urutan)
5 x 142857 = 714285 (angka sama beda urutan)
6 x 142857 = 857142 (angka sama beda urutan)
7 x 142857 = 999999 ( waw......suatu hasil yangFantastis )


ada lagi lho.......udah tau belum?
bilangan sembarang jika dikalikan 9 maka jumlah hasilnya = 9
kita buktikan.....

1 x 9 = 9
2 x 9 = 18, jumlah 1 + 8 = 9
3 x 9 = 27, jumlah 2 + 7 = 9
4 x 9 = 36, jumlah 3 + 6 = 9
dst. sampai tak terhingga .....Ok khan ...
