Dear Hedy,
thank you for contacting us and your question.
Currently, to answer your question, our technology doesn't allow to recognize Math mixed with Text.
Nevertheless, for use-cases such as yours, you could add a custom lexicon, in which you add the terms you want to recognize.
E.g. you can add expresssions such as 3+2 in a lexicon ; you then compile this lexicon and add it to your configuration file:
-https://developer.myscript.com/docs/interactive-ink/2.0/android/advanced/custom-recognition/#lexicon
Note nevertheless there is one issue for the specific case of E=mc², as the square "²" cannot be recognized. The alternative (which I tried), consists in adding "E=mc2" in a custom lexicon. You will then be returned with E=mc2, which you can convert by yourself ad "E=mc²" if exporting.
Let me know if this helps.
Best regards,
Olivier
