The number of combinations of 7 numbers from 10 is 10C7 = 10*9*8/(3*2*1) = 120
There are a huge number of combinations of 5 numbers when using the numbers 0 through 10. There are 10 to the 5th power combinations of these numbers.
1000
There are 125970 combinations and I am not stupid enough to try and list them!

10,000
575757
It is: 9C7 = 36
Through the magic of perms and coms the answer is 729
64
There are 252 combinations.
When using the numbers one through seven, the total number of different combinations depends on how many numbers you want to select. If you're looking for all possible combinations of any length (from one to seven), you can calculate it using the formula for combinations, which is (2^n - 1) (where (n) is the total number of items) to account for all subsets except the empty set. Therefore, for seven numbers, there are (2^7 - 1 = 127) different combinations. If you specify a particular number of selections, the calculation would differ accordingly.
1,000. The list looks just like the counting numbers from 000 to 999 .
