-
- 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
-
-
- 1 x 9 + 2 = 11
- 12 x 9 + 3 = 111
- 123 x 9 + 4 = 1111
- 1234 x 9 + 5 = 11111
- 12345 x 9 + 6 = 111111
- 123456 x 9 + 7 = 1111111
- 1234567 x 9 + 8 = 11111111
- 12345678 x 9 + 9 = 111111111
- 123456789 x 9 + 10= 1111111111
-
-
- 9 x 9 + 7 = 88
- 98 x 9 + 6 = 888
- 987 x 9 + 5 = 8888
- 9876 x 9 + 4 = 88888
- 98765 x 9 + 3 = 888888
- 987654 x 9 + 2 = 8888888
- 9876543 x 9 + 1 = 88888888
- 98765432 x 9 + 0 = 888888888
-
- Brilliant, isn't it?
-
- And finally, take a look at this
- symmetry:
-
-
- 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 = ?
-
- You got it:
- 123456787654321
-
- And finally:
-
- 111111111 x 111111111 = ?
-
- Of course:
