Question

How many 7 digit is there in all

Answer 1

All the digits after first digit can be anything between 0–9, including both. The easy answer to this is to subtract the value of the largest 6-digit number from the largest 7-digit number. 9,999,999 - 999,999 = 9,000,000. Therefore, there are nine million distinct 7-digit integers....
