Congratulations all of this rare event that happens once in a hundred years!
The number eleven is the fifth prime number (contrary to popular belief, the number one ( 1 ) is not a prime number).
(2 digits) 11 x 11 = 121
(6 digits) 111111 x 111111 = 12345654321
(9 digits) 111111111 x 111111111 = 12345678987654321 |
