Calculator Necktie
This tie includes all of the high-end calculators that I have used as an engineering student, a mechanical engineer, and a calculus teacher. The earliest calculator is a HP-45 scientific calculator that was purchased in 1973 for $400.00. It was worth every penny. The other calculators are graphing calculators: the HP-48sx, HP-48gx, TI-89, TI-89 titanium, and the TI-nspire. Also included is a Picket slide rule.
