The background of is run by George Kinnear and Steven O'Hagan.

Our efforts started in 2003, when we were both in S5 studying Highers. We had typed up some notes for our own revision, and created a website on free web space to share them.

Encouraged by the positive feedback people were sending, we bought the domain name '' and began adding new features to the website.

We have also launched HSN extra, to provide mathematics teachers with additional resources. The aim of HSN extra is to generate income which will cover the cost of providing the free resources.
