123456 + 987654 = 1111110
1111110 - 123456 = 987654
123456 - 12345 = 111111
So, 1234560 - 123450 = 1111110
1234560 = 123456 * 10
123450 = 123456 - 6
So, 1111110 = 10 * 123456 - (123456 - 6)
Thus, 987654 = 1111110 - 123456
= 10 * 123456 - (123456 - 6) - 123456
= 10 * 123456 - 123456 + 6 - 123456
= 123456 * (10 - 1 - 1) + 6
= 123456 * 8 + 6
Similarly for the rest where 1+9 = 10, 12+98 = 110, ..., 123456789 + 987654321 = 1111111110.
