If you feel linking to trevorpythag.co.uk from your site would add value to your readers please add a link (and if you let me know, using the comments below I will be able to look at your site and see if I think it is suitable for being linked to from this site).

If you do link to this site it would be preferable  (though its fine if you don’t) to use the text “Trevor Pythagoras: Maths help and tutorials” and make the URL “http://trevorpythag.co.uk”
