Hand on heart: who here, honestly, without any prior research [to learn what the hell i'm even talking about] or practice [to polish a long-dormant skill], could today, if presented with a mathematical question, solve it using [any or all of]:

1. pencil, paper, long-division & multiplication, BOMDAS?
2. log-tables
3. slide-rule

🤨

#LongDivision #LogTables #SlideRule #mathematics

Subsidiary question: how many more years/decades before nobody alive knows any of those? 🤷‍♀️
