Remember calculators were very expensive at the beginning and as time progressed the cost fell.

How well I remember. I took a statistics class in college using a Versalog slide rule while nearly everyone else in the class had one of those big expensive calculators. I got an "A" BTW.

I prefer an old fashioned slide rule.

I remember when the (one) electronic calculator for my sophomore engineering class was glued to the lab table
and one signed up to use it. i then purchased an hp-21
circa ‘76. 300 bucks.
