Wikipedia states that in mathematics, **permutation** involves arranging all members of a set into a sequence or order, or **rearranging** (reordering) its elements if already ordered, termed **permuting**. InÂ mathematics, aÂ **combination**Â is a selection of items from a collection, such that (unlikeÂ permutations) the order of selection does not matter. Getting answers and workings (steps) for permutation and combination problems in Nickzom Calculator – The Calculator Encyclopedia is very simple and I would very much love to show you how you can do this easily.

For permutation and combination calculations, you can access **Nickzom Calculator**Â (The Calculator Encyclopedia) via any of these channels:

Web â€“Â https://www.nickzom.org/calculator-plus

First and Foremost, proceed to the **Calculator Map,Â **under the Mathematics section click on **Permutation|Combination.**

Let’s begin with solving a problem on **Permutation**. I hope by now you do know the value of **n** and **r**

Click on Permutation

An interface for you to enter your values of **n** and **r** is displayed for you.

Now, enter the values.

Finally, click on Calculate

Clear as crystal, it properly displays the formula, workings, and steps for you.

Great, moving on to **CombinationÂ **navigate back to the Permutation and Combination page and click on Combination

The combination interface is displayed for you to enter the values.

Enter the accurate values according to the **n** and **r** parameters.

Lastly, click on **Calculate**

Once again, the result display clearly shows the outcome.

Thank you!
