Every number between 1000 and 9999 inclusive. Also every number between -1000 and -9999 inclusive.
Interesting.Social Security numbers all have the form: (3 digits) - (2 digits) - (4 digits).That's 9 digits altogether. If you ignore the dashes, you get: xxx,xxx,xxx .With 9 places, there are 1 billion possible different numbers.

Without repeats there are 4 × 3 = 12 possible 2 digit numbers. With repeats there are 4 × 4 = 16 possible 2 digit numbers.
456, 546 and 564 are three of the four possible even numbers.
To form whole numbers using the digits 2, 4, 6, 8, and 0, we must ensure that the number does not start with 0. The valid digits for the first position are 2, 4, 6, or 8, giving us 4 choices. After selecting the first digit, we have 4 remaining digits (including 0) to arrange in the other positions. Therefore, the total number of whole numbers is calculated as (4 \times 4!), resulting in 96 possible whole numbers.

If you mean, "What is the largest number of digits possible in the product of two 2-digit numbers" then 99 * 99 = 9801, or 4 digits. Anything down to 59 * 17 = 1003 will have 4 digits.
There are 2941 4-digit numbers such no two of its digits differ by 1.
6*5*4*3*2*1=720 possible numbers

im assuming that any charcter can be a number or a letter: (24letters*10 possible numbers)^(4 digits)= 3317760000 possible combinations.
It can have 4 digits, because the highest possible two digit numbers 99*99=9801.
To find the even two-digit numbers where the sum of the digits is 5, we need to consider the possible combinations of digits. The digits that sum up to 5 are (1,4) and (2,3). For the numbers to be even, the units digit must be 4, so the possible numbers are 14 and 34. Therefore, there are 2 even two-digit numbers where the sum of the digits is 5.
3000 and 6000 both have 3 0's, so they are out. The numbers between them all start with 3, 4, or 5, followed by 3 digits. There are 9 possible digits for the hundreds place, which leaves 8 for the tens and 7 for the units digit. The answer is therefore 3 x 9 x 8 x 7 = 1512 Answer 1 ======= There are 4 possible first digits, 9 possible second digits, 8 possible third digits and 7 possible 4 digits, making a total of 4 x 9 x 8 x 7 = 2016.
The possible 4 digit codes using the numbers 0-9 are every number between 0 and 9999. For numbers that have less than 4 digits, just precede the number with 0's. 10,000 possibilities
The answer to this is .... all the numbers between 999 and 10000
