Why? I've done calculus and analysis in college and no one has ever used a calculator, I'm not even sure what you would need one for, can you give me an example (seriously curious) The only time I remember needing a calculator in my entire education was some circuit theory because those Thevenins and Nortons get real ugly real fast (but even then you only need +,-,*,/)

This is not calculus specific, but how did you look up logarithms? With printed tables??

The same way as pi, e and other constants, log(17) is just that. I never had to convert them to some decimal approximation in calculus classes

Edit: Ok, I remember now there was a statistics exam when we had something like Student's t-distribution tabulated on the exam sheet but I had to scrape my brain to find an example, it does happen though

Oppositely here in Japan (where Casio locates), high school students usually don't use calculators on math/physics classes.

That's interesting and somewhat surprising to me. Do they use slide rules and/or function value tables printed on paper?

Not sure about Japan but in Poland the variables in problems are either symbolic and you solve it symbolically, or if they are given as values then they are usually chosen just right to not make arithmetic much of a bother (that actually results in a fun 'sanity check' that if you start getting something waaay crazier than 'normal' you double check if you didn't screw something up somewhere along the way or if there is a better way to solve it).

But everyone is taught to only substitute variables for values at the very, very end so calculators are not needed at all. At some point in education there is no point in testing arithmetic skills over and over again, the problems and the methods of finding out solutions to them are what matters

Last year I bought I used TI for my daughter who needed it for school. I got her the oldest version, the one which takes AAA batteries and communicates with the outside world through a serial link. A project like this brings to mind the possibility of stuffing a Raspberry Pi Zero in the battery compartment, hooking it up to the school WiFi, using a terminal app on the calculator to communicate with the Pi and in that…

I cheatet so much with my TI. In every class we were allowed to use a calculator I would literally code everything relevant for the test into this small thingy. I still think I better memorized some of the things as my class mates.

Also I loved how it doesn't really communicate except with a cable no one had. So nobody expected me to share my 'cheats'

That makes me think that a solar interntet is possible, perhaps routers and less intensive webpages may start moving if there was a value proposition for their owners. Sure it's not a whole solution just yet, but it's a start.

Lowtech Magazine has a mirror of their site hosted on a laptop and fully powered by solar that's been running for a few years now.

We were allowed to use calculators when I took my school exams in the uk. But our exam questions often asked us to give the answers in surds i.e 3/4*√2 not as a decimal which our calculators couldn’t do then. Our teachers told us there would never be a question where the answer couldn’t be expressed cleanly using either fractions or surds, that we should practice doing the maths and show our workings on the exam paper and that if we were using a calculator we were wasting time doing data entry as the actual addition / division / subtraction would never be hard enough to justify it. We memorised a table of surds for 30º 45º and 60º angles but I’ve forgotten why now. Also they hard reset our calculators as we went into the exam.

You are making the assumption that the user has some modicum of control over the browser's configuration.

No I am not. Users who require accessibility have it setup in their MacOS/Windows settings. It's a global setting for them. It's not website specific.

Users may access the site through a third-party device that they cannot configure, for example in a kiosk setting.

One of my proudest cheats was cramming the keywords of an entire presentation in French on a tiny round piece of paper, stuck to the glass of my wrist watch, so I could literally cheat while the whole class and teacher were watching me. Somehow I actually got away with multiple glances, only receiving a single remark about "being a bit too focused on the duration of my presentation". My cousin, who has always did hav…

How is having the transcript of the presentation cheating and not just being prepared?

In the same way that my ability to use WolframAlpha to answer physics questions in no way qualifies me to say “black holes don’t sound like they could work, surely the way the in-falling particles get an increasingly well defined velocity as they reach the event horizon causes their position to become increasingly undefined until they are almost certainly nowhere near the black hole?”, which is the kind of thing I tend to say because I don’t have a physics degree, and given how physicists generally respond when I say stuff like this there’s a 5% chance I’ve said something interesting and a 95% chance I’m as wrong as 90s Hollywood script writers were about computers.
