Thanks.

Since I use ConTeXt to typeset math formulas frequently, I want to
know more about this. Why \AA doesn't work?

\AA is defined in plain TeX, and I think all plain TeX macros should
work in ConTeX. Am I right ?

Hi,

you should also use the \text macro to write normal text in math mode.

\starttext
$$\text{\AA}^{\text{\AA}}$$
$$\Angstrom^{\Angstrom}$$
$$\text{\Angstrom}^{\text{\Angstrom}}$$
\stoptext
