Learn and know what is the **permutation meaning** in mathematics. In class 11 and also for IIT JEE exams permutations and combinations is one of the important chapters and also very interesting chapter.

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”

Example:

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.

Let

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**.

Note:

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**.
