2025-07-07 - Math riddle
I am happy that everything went great today. I didn't feel stressed or anxious, I was a bit confused on what to do at the beginning but the feeling went away and I already feel comfortable in the office.
I'll write some more thoughts in the following days, right now I am puzzled by a riddle written in the blackboard of the office, and it goes like this:
Gauss and Euler are playing a game, there are two secret numberrs \(p\) and \(s\) between \(2\) and \(99\). Gauss knows the value \(g = p*s\) and Euler knows the value \(e = p + s\). Then they say to eachother:
Gaus: I don't know p and s Euler: I am not surprised Gaus: Now I know Euled: Now I know too
What are \(p\) and \(s\)?
I have been playing with numbers for a few hours but I can't figure this out!
