I never got the hang of the slide ruler and never trusted a calculator. I still do everything in my head. Thank goodness I never need anything calculate! what is the quadratic formula?
My slide rule was fun and still hangs by my desk.
EXACTLY! That’s real learning!
Loved my abacus
You may find out attrition has taken it’s toll.
I still have 2 sliderules, but can’t remember how to use them. I still use paper and pencil more than an electronic calculator.
