99

9 x 111 = 999 To simplify the sum, think of it as making 99. 9 x 11 = 99 Then multiply the answer (99) and 11 by ten. That is your answer

999+99+9+9+9

The sum 9 + 99 + 999 + 9999 + 99 999 + .... where the last number to be added consists of nine digits of 9 becomes: (10 – 1) + (100 – 1) + (1000 – 1) + (10 000 – 1) + ... where the last multiple of 10 has nine zeros. There are nine pairs of brackets altogether. Add the multiples of 10 first and then subtract 9: The digit 1 appears 9 times in the final answer.
