Interactive PDF Formulas
In Acrobat it is possible to set up simple math formulas such that when a user fills in a box, it auto fills some other boxes. Why can't I just do that in InDesign?

Only 3rd party plugins are available ( Probably this would help a bit - https://scand.com/products/mathml-kit/. Though it doesn't mean to edit formulas at least you don't need to convert them to .eps or .pdf to get high quality print.
