It depends on whether the digits can be repeated and on whether you consider numbers that start with a leading zero to be a different "combination." For example, is 0123 a different combination than 123?

* * * * *

In a combination order does not matter. 1234 is the same as 2341 or 4213 etc.

Each of the digits 0-9 can either be in the combination or not in it. There are, thus, two options for each of 10 digits. This gives a total of 210 = 1024 combinations.

Note, however, that one of these combiations will be the null combination. That is, it will contain none of the digits. If that is to be excluded you will have 1023 combinations.
