There are 9 1-digit numbers and 16-2 digit numbers. So a 5 digit combination is obtained as:
This scheme does not differentiate between {13, 24, 5} and {1, 2, 3, 4, 5}. Adjusting for that would complicate the calculation considerably and reduce the number of combinations.

The sum you require is 4!/2!2!, which is 6. This means there are 6 different two-digit numbers. * * * * * Wrong! The above formula is for the number of combinations, not permutations. However, since the number 23 is different from the number 32, you require permutations and not combinations. There are 4*3 = 12 23, 25, 27, 32, 35, 37, 52, 53, 57, 72, 73, 75.
A 25-digit number is typically referred to as a "25-digit numeral" or simply a "25-digit number." In mathematics, numbers are typically identified based on the number of digits they contain, such as single-digit, double-digit, triple-digit, etc. The specific term used may vary depending on the context in which the number is being discussed.
The middle mber becomes the primary. Sort by that and then sort by the numbers to the left and then the numbers to the right. Example: 12-34-56 98-76-54 11-22-33 21-25-33 23-25-33 becomes: 11-22-33 21-25-33 23-25-33 12-34-56 98-76-54 Easy Schmeezy!

There are 480,700 combinations and I am not going to even try to list them!

There are 36 such numbers.There are 36 of them.

To calculate the number of different combinations of 5 numbers chosen from 1 to 25 without repetition, we can use the formula for combinations: nCr = n! / r!(n-r)!. In this case, n = 25 (total numbers) and r = 5 (numbers chosen). Therefore, the number of combinations is 25! / (5!(25-5)!) = 53,130 different combinations.
Assuming you meant how many combinations can be formed by picking 8 numbers from 56 numbers, we have:(56 * 55 * 54 * 53 * 52 * 51 * 50 * 49)/8! = (7 * 11 * 3 * 53 * 13 * 51 * 25 * 7) = 1420494075 combinations. (Also equal to 57274321104000/40320)
