"Permutations" do consider the order. If you want the order ignored,
then you're looking for "combinations".
3-digit permutations, repetition allowed: 9 x 9 x 9 = 729
3-digit permutations, no repetition: 9 x 8 x 7 = 504
3-digit combinations, no repetition = 504/6 = 84.
There is only one possible combination as a combination is the same no matter what the order is. There are 120 permutations, which is where the order does matter.
10! permutations of the word "Arithmetic" may be made.
3x2x1=6 permutations.
There are 9 * 8 * 7, or 504, three letter permutations that can be made from the letters in the work CLIPBOARD.
5*4*3*2*1 = 120
It depends on how many digit you are choosing from.
There is only one possible combination as a combination is the same no matter what the order is. There are 120 permutations, which is where the order does matter.
There is only one combination. There are many permutations, though.
10! permutations of the word "Arithmetic" may be made.
Given the individual digits: 4, 6, 9, 1, and 3,the number of 4-digit permutations is (5! / 1!) = (5 x 4 x 3 x 2) = 120 .The number of combinations is [ 5! / (1!4!) ] = 5 .
Using the eight digits, 1 - 8 ,-- There are 40,320 eight-digit permutations.-- There is 1 eight-digit combination.
There are 7893600 permutations.
There are 5,273,912,160 permutations of 5 numbers out of 90.
In case of digits or numbers, when we say combination, since the order of the numbers matters, we really need to find the permutations. For example, 12 and 21 are two permutations and not combination. The permutation for 10 digits chosen 5 ways is 10*9*8*7*6, which is 30240. But how many are there in whole like four digit has 24.

To calculate the number of different 4-digit combinations that can be made using numbers 0 through 9, we use the concept of permutations. Since repetition is allowed, we use the formula for permutations with repetition, which is n^r, where n is the number of options for each digit (10 in this case) and r is the number of digits (4 in this case). Therefore, the number of different 4-digit combinations that can be made using numbers 0 through 9 is 10^4, which equals 10,000 combinations.
