- "Plus is an internet magazine which aims to introduce readers to the beauty and the practical applications of mathematics. A lot of people don't have a very clear idea what "real" maths consists of, and often they don't realise how many things they take for granted only work because of a generous helping of it. Apparently, some people even have the idea that it's boring! Weird. Anyway, we hope that even if you're such a person now, you won't be after looking through one or two issues of Plus, and that you'll come back and read future issues as they come out."
