Hi Derek, There are basically two ways to integrate math and text. The first way is to mix the MathML with some other document oriented markup language like HTML. Thus, your example would get encoded as <html> ... <body> ... <p>What does <math>....</math> calculate to?</p> ... </body> </html> The up side is that this is really how MathML is intended to be used. The down side is that it is a pain to get a browser to display this properly. As you presumably know, to display this with WebEQ you would need to pass the MathML as a parameter in an applet tag, and getting the dimension of the applet to match the equation is a pain. The alternative is to abuse the MathML <mtext> element, and force the surrounding text to be part of the equation. <math> <mtext>What does </mtext> <msqrt> <mrow> <mn>1</mn> <mo>-</mo> <mn>2</mn> <mi>x</mi> <mo>+</mo> <msup> <mi>x</mi> <mn>2</mn> </msup> </mrow> </msqrt> <mtext> calculate to ?</mtext> </math> The up side of this method is that then your question is self contained, and can be displayed in a single applet or plug-in. The down side is that you will probably end up tweaking the spacing between the text and the equation (using named spaces like   since plain whitespace in MathML gets telescoped), and it doesn't scale very well. Hope this helps. --Robert ------------------------------------------------------------------ Robert Miner RobertM@dessci.com MathML 2.0 Specification Co-editor 651-223-2883 Design Science, Inc.
