Is there a way to display mathematical equations in a manner in which we would naturally write them or see them displayed in books (fractions, radicals, integrals, etc...)?

I have the need to display physics equations along side regular text for an application I am developing. Readability is paramount. Writing equations in a single line of text with parenthesis, slashes, etc is not acceptable.

If necessary, I would be willing to display the equations as an image file, but would prefer a text or MathML-esque solution.

Thanks!
