New-to-me, from TechBook: Over 5,000 Calculators! Inside Germany’s Most Unusual Tech Collection. “‘I received my first pocket calculator as a gift from my father,’ recalls Gerhard Wenzel from Solingen. ‘It was a device from Quelle’s own brand, Privileg, an 872 MD.’ Naturally, the first item in his collection is also featured in his online collection.” This is clearly a very old site and […]

AI Today, Calculators Back in the Day

An article about the dangers of AI dependency reminded me of how I encouraged a middle schooler to do algebra by hand in my senior year of high school.

https://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

I got this TI-85 for the 1st year of gymnasium back in mid-90s. It has served me through many schools and later jobs and I absolutely adore its functional simplicity even when it can do a lot. #ti85 #calculators

@NoveltyBot
Still got mine. Still works.
1979 is a VERY late date to still be selling these. I was already on my 3rd or 4th electronic calculator by then!

High end calculators should have a boss key.

The TI-34 is a fairly basic scientific #calculator. I’m a big fan because it’s easy to use and not overwhelming.

I was reading the manual and discovered it has two functions:

ipart(x)
fpart(x)

These return the integer and fraction parts of x.

ipart(2.34)=2
fpart(2.34)=.34

Great! So, uh.. What are these typically used for? Why include them on such a *basic* calculator? #calculators #ticalc #ti34 #matheducation #mathchat
