Davide P. Cervone’s html with internal javascript ([https://groups.google.com/g/mathjax-users/c/jUtewUcE2bY/m/0-sg2F2aCAAJ](https://groups.google.com/g/mathjax-users/c/jUtewUcE2bY/m/0-sg2F2aCAAJ)) allows renumbering of mathjax equations. The output gives (with my comments on the left) – ![image](https://canada1.discourse-cdn.com/flex036/uploads/pinegrow/original/2X/4/47d46458c68229a04e0cdaeb736cdd59b186c516.png) **How can I create a stand-alone javascript that does the same thing?** As an attempt, I extracted the following from Cervone and saved to number\_equations.js – ```auto ``` This is called by replacing everything in Cervone’s html between ` ` with – ```auto Equation numbers by section ``` This gives formatted mathjax equations but without any numbering – ![image](https://canada1.discourse-cdn.com/flex036/uploads/pinegrow/original/2X/e/eca7dd6acdbdfd288c05ce3c3274fe1a50b49f02.png) I suspect I’m missing something in number\_equations.js. (I know little about how to do this so please be explicit with any suggestions.) Thanks, Don C.
