I want to get a sign of angstrom in an math formula, here is my example:
and the error message:
systems         : begin file d at line 1
! Please use \mathaccent for accents in math mode.
\dochar #1->\char
\dobuildtextaccent ...{\let \char \normalaccent #1
                                                  \let \char \normalchar #2}
l.2 $\AA

I can use \AA successfully in text mode.
Is there anything wrong with my tex file?
