Another Fun Numbers Trick
Here is a fun numbers trick. The result will always include the numbers 1, 2, 4, 5, 7, 8 (6 in total)

Choose a number between 1 and 6
Example: 4

Multiply the number by 9
4 x 9 = 36

Multiply the new number by 111
36 x 111 = 3996

Further multiply the new number by 1001
3996 x 1001 = 3999996

Divide the new answer by 7
3999996 / 7 = 571428 (notice that the answer contains numbers 1, 2, 4, 5, 7, 8)
