[Updated 2012-01-13].
As I began to write my Decoded Science article, "An Introduction to Conditional Probability in Mathematics", I wanted to achieve two online writing tasks.

First, I had to test the HTML for the "is an element of" symbol. Second, I wished to lay claim to my original "artwork" based on a spreadsheet I developed.

The Element Symbol in HTML

This is the "Custom HTML" widget as provided by Weebly.

My first guess is that the "Element" symbol might be an ampersand followed by "elem;". Here goes: ( &elem; ).

Success or fail? FAIL!

I then researched this in a reference site. It should be an ampersand followed by "isin;" ("is in"). Here is is: ( ∈ ). SUCCESS!

I based this test on a WordPress plug-in for symbols that calls the Euro coin symbol an ampersand followed by "euro;". Here goes: ( € ).

I Hereby Claim Original Artwork

Claiming original artwork is simple: just be the first to post your home-made image online.

As always, I also promote my article in DeHaan Services ("Introducing the Math of Conditional Probability") and in my Xanga blog ("Starting with Conditional Probability").

(Updated 2012-01-17) As I explain in "Preview of Non-Commutative Conditional Probability", I will also include a link to one article that I used for reference:
Weisstein, Eric W. "Conditional Probability". MathWorld--A Wolfram Web Resource.

Writing Tip

Today's writing tip is: do your research if you need something. I found the "element is in" symbol in the W3Schools site's "HTML Symbol Entities Reference" page.

    Flexible Sidebar

    Weebly's "Blog Author" widget from the Blog Sidebar's Elements menu provides a lot of flexibility. You can change both the title and the text.

    It has all the capabilities for text editing that you find in most Weebly text widgets.

    At this point, I don't see a way to code any HTML in this widget.

    The "Picture" does what you expect: it displays an image of your choice. I just added my home-made picture of "Copyright DeHaan Services 2013" as the top element in this sidebar on Jan. 22, 2013.

    The "Search Box" is a "Pro" feature; if you're paying for Weebly hosting, it may be worthwhile.

    The other widgets are pre-programmed to do what they say.
