Hii! I'm very sorry if this is the wrong place to post this question but i didn't really dare ask in the more serious math related subreddits.

Im dating a guy that I know likes math, and I think know it on a higher level but not sure. He does not have a degree at least. (I'm 22 and he's 27 if it matters lol)

His birthday is next week and I'm going to make a birthday card with a frog on (inside joke), his favorite color as backround and I was thinking of having the frog read a book with some math equation inside. What would be a good one? Orrrr is there some kinda question I can ask him to get him to tell me his favorite one? (Is that even a thing? A favorite equation?)

Otherwise would appreciate some tips on what to ask to get him to talk about it more for general conversation!

Thank you for anything I get 🫶
