Mathematicians express amazement similarly to others, often using "Wow!" but sometimes adding a playful twist like "Wow factorial." The discussion highlights the humor in mathematical expressions, with participants joking about the implications of using factorials in everyday language. There is a lighthearted critique of how exclamation points can confuse meanings, especially in contexts like children's ages on a TV show. Suggestions for clarity include using "factorial-free" keyboards to avoid misunderstandings.
