Mike,
This is a hard way to learn it, anyway seeing a simple thing working puts a smile on face:)
OK lets make it work at least:
-Under inetpub\wwwroot create a folder say named "MikeTest" (wwwroot would do but we don't want to fill test stuff there).
-In your new folder create 2 text files (right text files so you can dblclick to edit)
-Put your codes into those 2 files (HTML stuff into one and aspx code stuff in other). BTW probably it only doesn't display right here. Check first line of your aspx code. It should have a closing tag ( <%@Import Namespace="System.Decimal"> ).
-Rename your text files to MathTest.htm and Math.aspx respectively (confirm to dialog about changing extension)
-Open a browser session and navigate to address:
http://localhost/MikeTest/MathTest.htmDon't worry if it gets too long to calculate first one. ASPX is being compiled for the first time.
