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


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=123456787654321


111111111x111111111=12345678987654321


Brilliant, isn't it?
