Multiply 37,037 by any single number (1-9), then multiply that number by 3. Every digit in the answer will be the same as that first single number

If you multiply 111,111,111 by 111,111,111, you get 12,345,678,987,654,321.

Fnatastic #9. Mulitply it by ANY number, the digits of the product add up to 9.
EXAMPLES:
9 X 5=45 (4+5=9)
9 X 9=81 (8+1=9)
9 X 37=333 (3+3+3=9)
9 X 145,689=1311201 (1+3+1+1+2+0+1=9)
9 X 65,382,554=588442986 (5+8+8+4+4+2+9+8+6=54 ... 5+4=9)
It always works!
