This web page is practical in nature. I cut and past code into html or xml documents. So all the mathematics on my website is done through cutting and pasting to a text editor.
MathML needs to appear inside the MathML tags and the html needs a header to tell the browers about MathML.
Not everything goes smoothly. Space sometimes does not work correctly on my browser. Often I use the primative   outside the mathml tags to get spacing.
You will notice that I combine mathml with css stylesheets. My main purpose of mathml is to display mathematics. MathML is also used for interpreting data - I do not use it for this at all.
There are two ways of doing a power, I almost always use the longer way because it produced better results in the browser that I use. See the right hand column under Syntax.
The Syntax section gives common maths formatting problems and a MathML solution.
People crap on to me about exact definitions and meanings of symbols as though they are sacred. This dumbing of ideas I will not tolerate, a tool should allow the user the freedom to do things.
Redefinition of symbols is necessary because there will always be a limited number of symbols. Different fields of mathematics use the same symbol to do different things.
The issue of MathML fonts not being displayed correctly on the Mozilla browser was because Mathematica refused to allow the distribution of their fonts, instead requesting each individual to personally visit their website and personally download and personally configure the fonts(a real pain in the arse, I could not get it to work on my linux box because I just did not know how to do it). This damaged the credability of MathML to no end, I have always been saying to mathematicians that this is a tempory thing (over 4 years now) but what can you do with a corporation like Mathematica, they should never have been alowed to put the fonts in in the first place. Free software is free software.
Finally I am shying away from the square root symbol because of the fonts but also because it detracts from the maths meaning. A half is much more informative and lends itself to other maths operations. Sometimes these are the real issues in mathematics, how can it be used to better do a job.
