## Challenge 1
How about we create a counter that counts backwards from 10 to 1? Let's add a while loop that executes only when `count` is greater than 0.

## Challenge 2
Inside of the while loop, let's add `pause->(1000)` so that we have a pause between each number as it's counting down. Also, let's show `count`!
Inside of the while loop, let's add a ``||basic:pause||`` that waits for one seccond so that we have a pause between each number as it's counting down. Also, let's show ``||variables:count||``!

## Challenge 3
Now, we need `count` to decrease by one after the @boardname@ has displayed the value of `count`.
Now, we need ``||variables:count||`` to decrease by one after the @boardname@ has displayed the value of ``||variables:count||``.
We can do this by adding this line:
```blocks
let count = 0;
count = count + (count - 1);
```
