Permutation meaning in math

learn and know what is the meaning of permutation

The meaning of permutation is “arrangements”. I think arrangement meaning everyone knows. Along with the meaning of permutation we should also know its Definition.

Definition of permutation:

Permutation can be defined as “Each of the different arrangements that can be made by taking some or all the things at a time”


If there are 3 digits and by taking 2 digits at a time, how many arrangements can we made? When Repetition is not allowed i.e. the same digit we should not take again.


1, 2 and 3 be the three digits. Now let us take 2 digits from 3 digits and arrange them. We get

12, 13, 21, 23, 31, 32. Here, Each of these arrangements is called as a permutation.


We are not writing 11, 22 and 33 because repetition is not allowed, if it is repetition is allowed then we can write them.

I hope you have understood meaning and definition of permutation.
