# How to insert mathematical symbols in emacs

I'm writing an Asciidoctor file to take notes for statistics and would like to insert mathematical symbols like β.

Is there any way to do this without copy and pasting?

You can set the insert method with M-x set-insert-method RET tex. Then type \beta and watch it get converted.
It can be toggled and set with C-\!
Tested and confirmed that it compiles and renders properly using asciidoctor-pdf.
