**Permutations**" is a very simple mathematics topic. The scary name scares you. That's all.

Now let us study Permutations.

**What are permutations?**

They are the different arrangements.

**Different arrangements of what?**

Of any numbers, objects, colors, alphabets, etc.

**So exactly how do you arrange the objects?**

We arrange them by changing their orders. For example, there are three balls of colours red, green and blue. We can arrange them in different orders as follows:

- Red-Green-Blue
- Green-Red-Blue
- Blue-Green-Red
- Red-Blue-Green
- Blue-Red-Green
- Green-Blue-Red
