Better Math Equations   allows you to take your typeset languages and convert them to images to use inside of your slideshow.  Other features include the ability to reload a equation image and make changes and re upload to your presentation.   

Recent changes added the math equations data into the alt text, which you can see by clicking using control + alt + y.


Supported Languages are
-Latex
-AsciiMath
-MathML

Other Features

Examples
Tex
  --valid Tex equation

  x^n + y^n = z^n

  Tex type uses inline notation.  Which restricts what you can add in your equation.

  Add \[ ]\ will cause a error at the current iteration.
  Also many formatting tags and the use of usepackage will cause a error. Some of these feature i will include after i build a separate window to work on larger equations. 


MathML
   --Valid MathML

   <mi>&#x3C0;</mi>
   <mo>&#x2062;</mo>
   <msup>
     <mi>r</mi>
     <mn>2</mn>
   </msup>
   
   MathML doesn't need to have a <math> tag to be a valid equation.  

AsciiMath
  --Valid AsciiMath
   
  sum_(i=1)^n i^3=((n(n+1))/2)^2
