As far as learning goes, you can’t learn two things at the same time. The hour you spent learning Russian can’t be spent learning mathematics. Don’t put background Russian radio on while you learn mathematics. It will distract you from learning math.
You can learn a language in small intervals while you are on the go. Completing a Duolingo Session while you ride the bus is easy. Doing math while you ride the bus isn’t.
The second thing that takes time is memory interference. If you do Anki don’t learn 6 new Russian animal names at the same time. Duolingo get’s this very wrong...
Learning 6 animal names at once is much harder than learning 1 at a week at a time. I think outside of SRS books are written the way that the introduce multiple items of the same class because while the makes learning harder, hard learning decreases long term forgetting a bit.
I don’t think there meaningful interference between learning Russian and math.
In some fields of math a lot of literature isn’t published in English so, knowing other languages will help you. On the other hand I still don’t think that there’s memory interference.
If you learn a new English math term ideally you might want to wait a week or two till you learn the French, Russian or German term for the new concept. But two terms won’t be that big of a problem even if you don’t wait that week.

You cannot get a math phd at e.g. UCLA without a basic competence in one of {French,Russian,German}. There is a test!
