As the gang is coming up with a plan to save the day toward the finale
of the live action "Scooby-Doo 2: Monsters Unleashed," Velma is seen
making some sort of (pretend) calculation on an e6b flight computer /
slide rule.

Since I was a kid and fan of the cartoon when Scooby Doo was first on
tv, I really enjoyed this movie! :-)
