The only number with a 6 between 1 and 9 is 6.
Between 10 and 99, every number that ends in a 6 or is in the sixties will have a 6 in it. The former category has 9 numbers in it, the latter 10, but they overlap at 66 so there are 18 numbers total in the range.
Fromm 100 to 999, the number must have a 6 in either the ones, tens, or hundreds digit. 90 numbers have a 6 in the ones place, 90 again in the tens place, and 100 in the hundreds place. NOT including the number 666, there are 8 overlaps that have 6 in both the ones and tens place, 9 with 6 in the ones and hundreds place, and 9 with 6 in the tens and hundreds place. Finally, the number 666 was counted an extra two time. Subtracting all the double/triple appearances, there are 252 numbers with a 6 in this range.
Finally, add up all these ranges to get that there are 271 numbers numbers with the digit 6 in this range.
There are 2700 digits.
If by "between" you mean "between but not including", then the answer is 9999 - 999 - 1 = 8999.If on the other hand, you mean to include both 9999 and 999, then the answer is 9999 - 999 + 1 = 9001.
0
Two of them which are 1 and 2
1, 3, 9, 27, 37, 111, 333, 999
There are 2700 digits.
It is 4 and 1,000
Only 1 exists, and it is "999"
There are 999 numbers between 1 and 1000, which includes all the integers from 1 to 999. If you're asking about the count of individual digits used in writing these numbers, they collectively comprise a total of 2887 digits. This is calculated by considering the number of digits in one-digit (1-9), two-digit (10-99), and three-digit numbers (100-999).
9000 of them. All of the numbers 1 thru 9999 EXCEPT 1 thru 999. 9999 - 999 = 9000.
Assuming that 001, 080, etc are not allowed (that is a leading zero or two is not permitted), the smallest number with exactly three digits is 100. The largest number with exactly three digits is 999. So there are 999 - 100 + 1 = 900 numbers with exactly three digits.
10001
Well, let's see now . . .-- If you were to count from 1 to 9,999 you would count 9,999 numbers.-- The first 999 of them would have less than 4 digits.-- So (9,999 - 999) = 9,000 of them would have 4 digits.
2893 digits in all, made up as follows: 9 1-digit numbers (1 to 9) = 1*9 = 9 digits 90 2-digit numbers (10 to 99) = 2*90 = 180 digits 900 3-digit numbers (100 to 999) = 3*900 = 270 digit 1 4-digit number (1000) = 4*1 = 4 digits
-999
solution: we know that there are 25 prime numbers are between 1-100 and 168 prime numbers less than 1000. 100 x 100=10000(5 digits) 999 x 999=998001(6 digits) 1000 x 1000=1000000(7 digits) so our answer should be same as the number of prime numbers between 100 to 999. hence, 168-25=143. 143 prime numbers will be there less than 1000 whose square has 5 or 6 digits.
To find the total number of digits used to print the numbers from 1 to 11,521, we can break it down by the number of digits in each range. From 1 to 9 (9 numbers) uses 9 digits, from 10 to 99 (90 numbers) uses 180 digits, from 100 to 999 (900 numbers) uses 2,700 digits, and from 1,000 to 11,521 (10,522 numbers) uses 42,088 digits. Adding these together, the total is 9 + 180 + 2,700 + 42,088 = 44,977 digits.
