If you include the number 3,000, there are exactly 2,001 4-digit numbers between 500 and 3000.
All the numbers between 999 and 3000 are four-digit numbers. You need to subtract 3000 - 999 - 1. The extra -1 is to account for the fact that the numbers 999 and 3000, in this case, are not included.
There are 900 three digit numbers between 99 and 3,000 - ranging from 100 to 999

There are 449999 such numbers.
If you include the number 3,000, there are exactly 2,001 4-digit numbers between 500 and 3000.
There are 900 three-digit numbers, all of which are between 99 and 3,000.
All the numbers between 999 and 3000 are four-digit numbers. You need to subtract 3000 - 999 - 1. The extra -1 is to account for the fact that the numbers 999 and 3000, in this case, are not included.
There are 900 three digit numbers between 99 and 3,000 - ranging from 100 to 999
1000 to 2999 inclusive so 2000 numbers.
3000-999=2001.
2001 is the correct answer.

There are 900 three-digit whole numbers between 1 and 1000
Eleven digit numbers are those in the range between 9,999,999,999 and 100,000,000,000 exclusive. There are 90,000,000,000 of these.
There are 449999 such numbers.
√2000 ≅ 44.7 √3000 ≅ 54.8 The squares of 45 to 54 lie within the range 2000 to 3000. There are thus 10 perfect square numbers between 2000 and 3000.
