#19 Rollyo

Okay, getting the idea after playing for a bit. The hard part is the inspiration for what I regularly search for!!!

I've added a search roll for complex numbers (a new topic for my kids, and one where there are limited electronic resources at school) and have added sites with some nifty explanations (including a complex number calculator! How cool).

Sticking this one in delicious too.......
