[Blindmath] MathML and VOiceOver?

[Bill Dengler]

Additionally, it seems you need to interact with math twice or three times to move from term to term.
For example, on the simple mathematical facts page, the expression ax^2+bx+c required three interactions to move between ax^2, bx, and c. You should only have to interact once, nothing useful is contained within the other levels of interaction, they seem illogical.

What happens if you use VoiceOver’s navigation commands (Ctrl-Option-Left and Right-arrow) to read the text and the mathematical expressions? You should be able to interact with the mathematical expressions and then read them.
>> On other sites, MathML is not focusable; when VO encounters it the focus jumps to somewhere else on the page, making it difficult to read (or skip) the math. For example: http://math.stackexchange.com/questions/253997/how-to-find-the-sum-of-an-alternating-series
