If repeats are allowed than an infinite number of combinations is possible.

1.52415788 × 1018
1234567890-1234567856 = 34
1234567890 + 1098765432 = 2333333322
The number of combinations you can make with the digits 1234567890 depends on how many digits you want to use and whether repetition is allowed. If you use all 10 digits without repetition, there are 10! (10 factorial) combinations, which equals 3,628,800. If you are choosing a specific number of digits (for example, 3), the number of combinations would be calculated using permutations or combinations based on the rules you set.
If repeats are allowed than an infinite number of combinations is possible.
If there are no restrictions on the 'combinations' then there are ten choices for the first digit and ten for the second: 10 x 10. (This implies possibilities such as 22 and 77.) If the digits must be different in each combination then the number of combinations taking two at a time from ten is C(10,2) = 10!/( 2! ( 10 - 2 )! ) = 45.

Oh, dude, you're asking about combinations now? That's like asking me to count all the grains of sand on a beach. There are like a bazillion combinations for those numbers, so good luck with that. Just remember, math can be a real party pooper sometimes.
