HHC2021 Bob's Calculator Challenge

[rprosperi]

@Didier - Excellent find, thanks for sharing that here!! It answers a question lonnng left open; with 95k employees, I'd guess they made only about 50k units and then sold what was left through reliable, specialty channels like EduCALC. It's unlikely the janitors and HR staff needed a scientific calculator.

@Pauli - Thanks!! I was not sure if it would seem silly, so I'm glad lots folks enjoyed the Challenge (though I suspect there are still some of the former as well).
