# PGWS Challenges #1

With the lack of entries yet people telling me they are going to enter, I am going to extend this to the end of July. Get those footage in asap.

It has been a very long while from when I done a contest on Tweaked for your Pleasure but from feedback related to my puzzle ones, I have decided instead to do a gaming related set of contests this time which I am now calling PGWS: Challenges.

So lets kick the ball and get started.

You will need the following:

# Why we can’t divide by 0

Quite rarely do I ever do anything about mathematics on Tweaked for your Pleasure but today I got e-mailed a question and although I rarely do requests, I figured I might as well ask this.

This changed however when smart phones started to become more common and started using mobile internet for far more than just e-mail and the odd web browsing. Smart phones started to allow people to view the Internet in mostly the same way as they are used to at home.
