A lot of people think that recursion is too complicated for Year 7 students. But that's not true! Recursion can actually make solving problems easier.

Let’s take a look at how to find the factorial of a number $n$ using recursion:

1. Base Case: If $n = 0$, we just return $1$.
2. Recursive Case: We return $n$ multiplied by the factorial of $n-1$.

Another common idea is that recursion is always slow. This isn't completely right either. Yes, some recursive methods can take more time, but many, like quicksort, are both smart and fast.

Learning about recursion can really help boost your problem-solving skills!
