Math is unfortunately not a very popular language and, as a result, the ability to display it on the internet has been slow in development. There are formatting standards for a math mark-up language called MathML (as opposed to HTML where the 'ML' stands for 'Markup Language) as dictated by an organization called the World Wide Web Consortium but implementation of the standerized language in browsers has been slow. Beyond the fact math viewing is not as widely desired on the internet is the fact that math requires much more 'marking up' then many spoken languages. On Windows machines, private commercial organizations have created readers to display math (Math Player) and editors to create it (for Internet Explorer)...much like Adobe Acrobat Reader to read PDF documents (a free plugin) and Adobe Acrobat to create PDF documents (you pay for it). Mozilla, Firefox, and Netscape browsers were created by "open source" ( and non-commercial) organizations so, being less concerned about getting $ for all their hard work by having a large audience, they considered viewing math to be a high priority. Viewing MathML is intended to be standard in these non-commercial browsers.
Another consideration is the computer you are using to view internet pages. Although Apple computers have become amazing computers with their OS X operating system, they are still less mainstream and people still gravitate (no pun intended) to PCs. So even though a private organization has created Math Player for Internet Explorer, at the time of this writing, it only works on Internet Explorer for Windows machines. Below is a shopping list of free things for you to download and install which depends on your computer and your internet browser. You will need these items to take advantage of this site. Who knows...perhaps one day these will all be standardized and everything will be packaged with all existing browsers so that we don't have to worry about exceptions for this or that. In the meantime...find your set-up below and follow the instructions.
