If they hope to reach out to people and interest them in math and how practical it is, then not showing examples of this does a disservice to their goal. It's like playing World of Warcraft for me... I find it incredibly boring to play a game where the majority of what you do is "Gather/Hunt/Mine X units of Y and take it to Z". My friends who are into it say "Yes, but that's just the beginning... the real fun starts at level 60+". That may be true, but I'm unwilling to torture myself through months of "gameplay" just to see if at level 60+ I still find it fun. If it's not interesting from the beginning, what are the odds most people will stick around?
