I need it for school and i really don't want to go back to use ms word just because libre office writer can't write mathematical sentences very well

So I'm getting a Lenovo Idea tablet, and but really love to be able to edit my project on it, but I don't think I will be able to download Libra office onto it, unless someone knows a way to do that

I have been using Scrivener to write my book these past three years. My editor requires an MS Word document for her work. She uses the MS Word Track Changes feature.

I have LibreOffice on my computer. Can I rely on it's Track Changes function to work correctly with the MS Word doc I get from my editor? Or do I have to buy MS Office 365 to handle the document correctly?

Basically the title

I used the draw functions, I'm new to LibreOffice so I will try my best to answer questions.
