Seems unlikely with any sapient intelligence. If the intelligence understands mathematics then some form of communication will be possible. Consider:

  0 1 2 3 4 5 ...
  0 + 0 = 0
  0 + 1 = 1
  1 + 1 = 2
  1 + 2 = 3

There are only so many ways that you can express these ideas. With any kind of written language, or spoken language that can be identified as speech, it seems quite likely that we’d be able to discern the meaning of mathematical truths and statements like these - no matter how different the intelligence is from humans. Regardless of the symbols used or writing system, there will be certain commonalities that make it possible to find the meaning.

I would contend that for any human-level intelligence with a written mathematical language, if the intelligence wrote down their expression of the mathematical ideas above, we would be able to identify them and understand them.

I could see this being difficult if we don’t recognize speech or writing for what it is, though. But once we do I think the meaning of mathematics at least will be self-evident with study.
