    How many possibilities
    So I was bored. And I was wondering...
    How many possible combinations could you make of the numbers

    1, 2, 3, 4

    Like numbers like, 1234, 4321, 3241

    I'm curious

    Hi, Sodium!

    I found what is quoted below on the following site and thought that it was kind of cool!

    See How Many Number Combinations You Can Make - WebMath

    You want to see all possible permutations of these items:
    1, 2, 3, 4

    There are 24 possible permutations for these 4 items.

    For n items, there are n! (n factorial) ways of arranging them, when the order of your arrangements matters.

    n!=n × (n-1) × (n-2) ×... 1. Here 4!=4 × 3 × 2 × 1 = 24.

    Here are the possible permutations:
    1: 1 2 3 4
    2: 1 2 4 3
    3: 1 3 2 4
    4: 1 4 2 3
    5: 1 3 4 2
    6: 1 4 3 2
    7: 2 1 3 4
    8: 2 1 4 3
    9: 3 1 2 4
    10: 4 1 2 3
    11: 3 1 4 2
    12: 4 1 3 2
    13: 2 3 1 4
    14: 2 4 1 3
    15: 3 2 1 4
    16: 4 2 1 3
    17: 3 4 1 2
    18: 4 3 1 2
    19: 2 3 4 1
    20: 2 4 3 1
    21: 3 2 4 1
    22: 4 2 3 1
    23: 3 4 2 1
    24: 4 3 2 1

    First determine the first six from the number 1 figure.
    Then multiply by 4

    You get 6 times 4 = ANSWER 24 possibillities.

    I'm no whiz at math, but I think that the posters above coming up with the mathematical ways to figure out the problem are great! :)

    You're talking about permutations. N items can be arranged in n! Ways (where ! Is the symbol for factorial).
    For example, 5 items can be arranged in 120 ways and 20 items can be arranged in 2,432,902,008,176,640,000 ways.
