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 urutan)
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 yang
Fantastis )

ada lagi lho.......udah tau belon?
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 ...

ada lagi....
22 x 9 = 198, ..... cara cepatnya 2 x 9 = 18, lalu
selipkan angka 9 ditengah, jadi 198....ok

buktikan sendiri cara cepatnya berikut ini...
33 x 9 = 297, cara cepat 3 x 9 = 27, selipkan 9
ditengah
44 x 9 = 396
55 x 9 = 495
66 x 9 = 594
77 x 9 = 693
88 x 9 = 792
99 x 9 = 891

lalu bagaimana dengan 3 angka kembar yach ....???

sama aja tuch tinggal selipkan 99 ditengahnya....

gak percaya ....kita buktikan yach...
222 x 9 = 1998, cara cepat 2 x 9= 18, selipkan 99
ditengah
333 x 9 = 2997
444 x 9 = 3996
555 x 9 = 4995
