I have never used slide rules, but we did have abaci ( ? hopes it doesn't pluralise like octopus
) when I was at primary school. Graphing calculators were the norm whilst I studied my A-level Maths and Physics, however for some reason I seem to remember that they took them away in the statistics and mechanics exams and gave us log/trig/normal distribution tables instead. Probably the closest that I could get to appreciating the beauty of working with those tools. I suspect that the ability to simply press a button without understanding the function behind it could be the downfall of modern society
back to the Plot... My dear old aged Pa got a ZX81 when I was 8, it was fun to attempt to make it write rude words like "bum" and "poo" ( i WAS 8!!) all over the monitor.
It seems strange that back then we had more computing power in our house/street/village due to that one machine than I saw all the way till I was in Secondary education at school! Computing/IT/Programming were not even options, apart from some desultory prodding at "educational software" in a room of 12 BBC Machines between 34 kids. I suspect that the inability to press buttons to implement the understanding of the function behind the one button may also contribute to the above mentioned downfall!
