This is the second arithmetic symmetry that will equip your mind about how to manipulate numbers.
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
Another nice number play.
