To see an example set of equations and try them with IOS voiceover go to http://www.mathjax.org/demos/mathml-samples/ and set the render to MathML.

When flicking left and right, it appears an equation is a single object and voiceover reads the entire equation. However once you are on the equation, you may double tap it and go down a level to explore parts of the fraction, and each part may be double tapped to decend another level. An alternative way to explore the equation is that in the rotor you will find options for size of parts of the equation to navigate by if flicking up and down.

Quite where one might insert math on an IOS device I am not sure (IE. can you enter it in any edit box or must it be a math enabled one).
