Double Click to Zoom - Using MathJax Math Settings

Reading math online is sometimes difficult.  For example,

The Flat World Knowledge website uses MathJax to render and display math elements on the web.  If you RIGHT CLICK a math object you will be presented with a number of options.  

Choose Math Settings >> Zoom Trigger >> Double-Click

After doing this, you will be able to double click on a math element and it will zoom to 200% (or whichever zoom factor you choose.)

Click the zoomed in picture and it will go away and you can continue reading.

New Elementary Algebra Textbook Homepage

I have created a new homepage for our Elementary Algebra textbook.  You can still find worksheets in the course page found on this site.

http://edunettech.blogspot.com/p/elementary-algebra-textbook.html

Also, Intermediate Algebra will be published very soon.  I am excited for folks to check that out... it came out quite good. It is written as a perfect blend of the traditional and graphical approaches to the subject. No CAS required but certainly encouraged! In addition, I kept to a modular design so as to maximize the use of the FWK MIYO "make it your own" system.

Finally... truly viable alternatives to the existing expensive algebra textbooks currently on the market!
