$ C_1×V_1=C_2×V_2 $
Awesome it works. I just found something that makes entering equations much easier. I have a USB Bamboo Pen tablet and Windows 7 includes a math input panel. Windows recognizes handwritten equations and converts them to MathML. MathML stands for Math Markup Language. WordPress doesn't support MathML natively, but there is a plugin WP-Math-2. I write the equation with the pen pad, and insert it into Microsoft Word. Then I "paste as plane text" from Word to WordPress, and BAMM! beautifully rendered completely readable equations.
here is a real test. The Quadratic Formula:
$ X=(-b±√(4^2-4ac))/2a $ <<< Extra credit for remembering? lol
