The digit 8 represents tenths.

3 more than 5 is 8, so the tens digit is 8. The tens digit is,double the number of the ones digit, so divide 8 by 2 and you get 4. If you double 4 it is 8 so, the number is 84.

The digit 8 represents tenths.

To find that, simply take your largest 8-digit number: 99999999 And subtract your largest 7-digit number: 9999999 That leaves you with 90000000, or ninety-million.

Well, that depends on what rules you want to follow as far as formatting the number is concerned. Can the first digit be a zero? Can it be anything other than a 1?. That is, does it have to be a valid phone number? Let's assume that the first digit can be anything. We can work the answer out as follows: Total number of 8-digit numbers (with preceding 0's): 108 Total number of 8-digit numbers that have all unique digits: 10! / 2! Therefore, the total number of 8-digit numbers - allowing preceding 0's - would be 108 - 10!/2! = 100000000 - 1814400 = 98185600 Now, if you don't want to allow a preceding zero, then your first digit can only be 1-9. So instead we get: 9 * 107 - 9 * (9! / 2!) = 90000000 - 1632960 = 88367040
