According to Wikipedia,

In mathematics, the notion of **permutation** relates to the act of **arranging** all the members of a set into some sequence or order, or if the set is already ordered, **rearranging** (reordering) its elements, a process called **permuting**.

In mathematics, a **combination** is a selection of items from a collection, such that (unlike 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.

You can access **Nickzom Calculator** (The Calculator Encyclopedia) via any of these channels:

Web – https://www.nickzom.org/calculator-plus

Android (Paid) – https://play.google.com/store/apps/details?id=org.nickzom.nickzomcalculator

Apple (Paid) – https://itunes.apple.com/us/app/nickzom-calculator/id1331162702?mt=8

First and Foremost, proceed to the **Calculator Map, **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

As clear as crystal, the formula, workings and steps is properly displayed for you. I do hope you understand, right?

Great, moving on to **Combination **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, a display of the result is clearly shown.

Thank you!
