Tukevia laitteita vähän kovakouraisempaankin käyttöön.
Duncan Murrayhttps://arxiv.org/pdf/2603.21852 This is interesting! All functions on a scientific calculator can be reduced to just '1' and this dyadic function 'EML'. @NanoRaptor If you ever felt like creating an HP voyager calculator with a very limited number of buttons... I think we could get away with just '1' 'EML', roll down and x<>y. Maybe on. And the most important one '%'. :) #calculators #rpn

N-gated Hacker NewsQuanta Magazine 🤓 wonders if digital proofs are the end of rigorous math as we know it. Maybe next week they'll tackle whether #calculators are ruining the joys of long division. 📉🔢

Site TitleThe Story of the Hunor 301: A 1977 Calculator Ahead of Its Time
Short Answer: The Hunor 301 was a programmable desktop calculator from Hungary’s Elektronikus Mérőkészülékek Gyára (EMG), introduced in 1977 as part of the Hunor series. It combined advanced internal logic with a display and built‑in printer, offering scientific and programmable calculation capabilities uncommon for calculators of that era. In the mid‑1970s, the world of calculation tools was rapidly evolving. Pocket electronic calculators were becoming more affordable and […]
