Okay so I don't now if google issued this update because of my post but if we didn't have this previously and I was just doing things wrong we have quite decent mathml/mathjax support now, it's honestly quite impressive if this is an actual update. I can almost do all my webworks on my dynabook chromeos flex now. Almost. Some bug with webwork and espeak pronouncing letter by letter apparently for problems like peacewise function,
f(x) = \begin{cases}
19 & \text{ if } x \lt -8 \\
-x+ 11 & \text{ if } -8 \le x \lt 8 \\
6 & \text{ if } x =8 \\
11 & \text{ if } x \gt 8.
\end{cases}
And bug with the text app just announcing the first line of the f(x) and nothing after until the empty "end of text" announcement. Nice work if you've actually done it, Google.
