There are 24C12 = 24*23*...*13/(12*11*...*1) = 2,704,156 combinations.
With 4 digits you can have 24 = 16 combinations. 1 combination with 0 digits; 4 combinations with 1 digit: 1, 2, 4 and 8 6 combinations with 2 digits: 12, 14, 18, 24, 28 and 48 4 combinations with 3 digits: 124, 128, 148 and 248 1 combination with all 4 digits. In a combination the order of digits is not relevant so that 124 is the same as 142.

Yes, you can do 12 + 7 + 5 = 24

There are 24C12 = 24!/[12!*12!] = 2,704,156 combinations.
2,704,156
24C7 = 24!/((24-7)!7!) = 346,104.
4!=4x3x2x1=24
10 * * * * * That is just plain wrong! It depends on how many numbers in each combination but there are 1 combination of 4 numbers out of 4, 4 combinations of 3 numbers out of 4, 6 combinations of 2 numbers out of 4, 4 combinations of 1 number out of 4. A grand total of 15 (= 24-1) combinations.
There are many different combinations of six numbers, but the sum of those numbers would have to be 24.
24
It depends how many numbers are in your combinations: 0 or 24 there is 1 1 or 23 there are 24 2 or 22 there are 276 3 or 21 there are 2,024 4 or 20 there are 10,626 5 or 19 there are 42,504 6 or 18 there are 134,596 7 or 17 there are 346,104 8 or 16 there are 735,471 9 or 15 there are 1,307,504 10 or 14 there are 1,961,256 11 or 13 there are 2,496,144 12 there are 2,704,156 If by combinations you do not mean the mathematical selection of a subset of items from a set of items (where the order doesn't matter) but how many ways are there of arranging 24 numbers then there are: 24! = 620,448,401,733,239,439,360,000 ways.
1 and 11 and 21 and 31 and 42 and 12 and 22 and 32 and 43 and 13 and 23 and 33 and 44 and 14 and 24 and 34 and 416 combinations
There are 12 such numbers (excluding 24).
4! = 4*3*2*1 = 24 of them.
there are altogether 24 numbers between 9 and 32. by using nCr, 24C4 = 10626
