Honestly nothing in this article is even that bad, just some elementary group theory. If you wanted to, you could probably pick it up in a few hours. The math for the HE schemes themselves does rely on some intermediate level number theory though (e.g. Chinese Remainder Theorem in polynomial rings) and of course there's a whole formal language for the security proofs also.
