1 - even numbers in 1...9999 interval
9999 divided by 2 is 4999
2 - even numbers in 1..999 interval
999 divided by 2 is 499
Doing (1) - (2) = 4999 - 499 = 4500 even numbers in that interval.
500 of them.
From 1000 to 9999 (inclusive) there are 9999 - 1000 + 1 = 9000 integers. Half of which are even, half of which are odd. So the answer is 9000/2 = 4,500.
If you mean "between" 100 and 1000 to mean excluding 100 and 1000 then 449. If you want to include 100 and 1000 then 451.
Since 1000 is even, all of its multiples are even as well. Simply multiply 1000 by different integers, to gets its multiples.

Even numbers are those integers that end with 0, 2, 4, 6, or 8.
Since 1000 is even, all of its multiples are even as well. Simply multiply 1000 by different integers, to gets its multiples.
The even integers between -4 and 4 are: -4, -2, 0, 2, 4
There are 10 even integers between -10 and 10 (excluding -10 and 10).
405
18, 20, 22, 24, 26. 5 even integers
Between 13 and 15 there is only one even integer: 14.
4*5*5*5 = 500
