How to get Beamer Math to look like Article Math
I have been playing around with TikZ and am impressed.
I have noticed that the $A$ math mode syntax is using sans serif, italicized font. How can I switch it to use serif, italicized font by default whenever in math mode?
Note: This is not TikZ specific. Regular math display mode appears to have the same issue.
Update
It is a beamer-specific setting and probably has something to do with the \usetheme[default} setting. I will now look into the theme itself, but if anyone knows the specific setting to override the sans serif behavior it would speed me up.
