Finding Prime numbers using coding on Scratch!

In this tutorial I do my best to complicate the way to find a list of every prime number up to about 50,000 (I could probably do more on Turbo mode!)
This is a bit more advanced than the usual videos - but to be honest the coding is still quite simple, it's mainly understanding the loops that take place.
This is a project you can follow around with and use to create all sorts of mathematical investigations. There are loads more to do at www.mathsbtc.com
