9999
There are 10000 because there is 0001 to 9999 and then there is 0000.
The maximum number that can be formed is 9999. The numbers 'count themselves', except you must remember to include 0 (0000), so we get: 9999+1 = 10000 combinations. This can also be seen in terms of pure combinatorial mathematics as 10*10*10*10 = 104 =10000.
One solution: 0990 + 0000 + 0000 + 0066 + 0055 = 1111
If you count 0000 to 9999 you have 10,000. For whole numbers you have 9999. * * * * * Not sure about "whole" numbers. There are 10,000 in all, of which 9000 (from 1000 to 9999) do not have leading 0s.
4000 of them.

There are 9999 possible combinations starting from 0000 to 9999
9999
Not sure about the exact number but it is approx 1086.
10,000. from 0000 to 9999.
There are 10000 because there is 0001 to 9999 and then there is 0000.
If leading zeros are allowed, then there are ten thousand possible: 0000 through 9999. If leading zeros are not allowed, then it is 1000 through 9999, eliminating 0000-0999, and now there are nine thousand possibilities.
10,000 of them, from 0000 to 9999. However, most people would not count numbers with leading 0s, so that there would be 9000 4-digit numbers.
