Just considering the general situation, $ is hard for Org because it needs = to do =E2=80=9Cdouble duty=E2=80=9D as both a currency symbol in text, and math d= elimiters. This means that it can=E2=80=99t be consistent with how LaTeX works. However, `\( ... = \)' doesn=E2=80=99t and so Org can be much more consistent with LaTeX here. Besides which `$ ... $'= is a TeX-ism and `\( ... \)' is the /proper/ way of doing inline maths in LaTeX,= so really you should be reaching for those anyway. > I ask because if =E2=80=A6 breaks basic mathematics, I should either retu= rn > back to LaTeX for any serious notes or replace every =E2=80=A6 with =E2= =80=A6 in all my > Org files to avoid accidental breakage of mathematics in the future. Than= k you! I=E2=80=99d just use `\( ... \)' in future, and that way you=E2=80=99ll be = fine in LaTeX and Org =F0=9F=99=82. You might be able to use `org-element-map' to robustly conver= t from $ =E2=80=A6 $=3D to `\( ... \)'. All the best, Timothy --=-=-=--
