In my high school library, there was a copy of the classic book “Men of Mathematics” by E.T. Bell. Each chapter is a short biography of a notable mathematician of the past (and yes, they are all men). In the chapter on Carl Friedrich Gauss (1777-1855), I first encountered the famous story of how, as a 10 year old student, Gauss baffled his teacher by instantly solving a problem that the teacher assumed would occupy his student’s an hour or more.

In this post, I will describe Gauss’ insight, then show how a related problem can be solved by using some informed guesswork.

This post is about creating, displaying, and publishing documents that have mathematical content. This is a troublesome thing for mathematics and science workers, because most word processing systems treat math as an add-on or an afterthought, if they have any provision for it at all. Even when mathematics is supported, it may be difficult or impossible to do much more than print the document on paper.
