\bigskip 

\bigskip Two mathematicians are having a conversation. Mathematician A asks
B about his kids. B answers: "I have three children, the product of their
ages is 36." \ A says: "I still don't know how old your children are." \
Then B tells A the sum of his three kids' ages. A answers: "I still don't
know how old they are. Then B adds: "The youngest one has red hair." Now A
knows how old the kids are. Do you?
