It's Halloween night, and an adventure you never expected to experience is about to happen...

Your math teacher has given an unusual assignment for the holiday - give him a piece of candy, or do an enormous number of math problems! Unfortunately, your super-strict parents have forbidden you to go trick-or-treating, so it seems that you have no choice but to buckle down and spend the entire night doing math...

But after a strange visitor comes to your window, you find yourself transported to a strange and spooky world threatened by the evil Archfiend of Arithmetic! You'll need your math skills to overcome this villain - can you do it before you succumb to MATHPHOBIA?
