You may need to add four spaces before, or put backticks around, math fragments.

Custom superscript and subscripts (credit: /r/homeworkhelp):

Here's the syntax:

  • *_sub_* makes sub
  • *`sup`* and \^(sup) both make ^(sup)
  • *_sup_`sup` makes subsup*
  • *`sup`_sub_* makes supsub

If you have trouble with spacing, add some blank spaces with \ 

2300H becomes 2300   H
