In the attic of a friend, we found a postcard with inscriptions, and we think it might be codes that are part of a math puzzle. If there are people who know about this and can decipher it, thank you in advance for the answers.

Good evening!
No! No! No! It's not crypto!
These are mathematical symbols: membership, equivalence, and union symbols (used in algebra in set theory).
This means:
in the 1st brace: MM belongs to ED and ED belongs to MM
between the two braces the equivalence symbol
in the 2nd brace: ED united with MM and MM united with ED
Below there are symbols that I don't quite understand: maybe an infinite number next to Thousand (spelling mistake: thousand is invariable).
Your husband ...I can't decipher that (maybe: loves you)
We are approaching Valentine's Day: it's current!
