Oh, what a delightful question! If we take a look at the numbers from 1 to 99, we'll find that they have a total of 189 digits. Each number from 1 to 9 has one digit, numbers from 10 to 99 have two digits each. Just imagine all those lovely digits coming together to create a beautiful numerical landscape!

Not couting 1 and 1000, there would be 998 numbers.
Infinitely many. The number pi , for example, is between 1 and 1000 and, since pi is a transcendental number, it contains infinitely many digits. Plus, there are all the irrational numbers - each with infinitely many digits, and all the rationals with recurring decimals - again with infinitely many digits.

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).
There are 2892 digits.
I suggest you calculate (1) how many numbers are in total, and (2) how many numbers in that range do NOT have 6 as a digit. Then you can subtract the result of (1) minus the result of (2).
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

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.
Using only arrangements of the given digits: without repeating digits, 15. with repetition, 39. The answer does not include numbers such as 2^3 = 8 or 3^(2+1) = 27
There are 116 1s in the first 1000 digits of pi.
When counting the digits from 1 to 1000, the digit '0' appears the smallest number of times. It appears only in the numbers from 10 to 1000, specifically in the tens and hundreds places, but not at all in the numbers 1 to 9. In contrast, digits like '1' through '9' appear more frequently due to their presence in many numbers throughout the range.
